Direct replacement for Apple M1 Chip is near. There were some M1 Chips versions like M1 MAX and M1 ULTRA that were upgrades of the existing M1 chip, but the new and upcoming M2 is something different and it is aiming to replace M1 completely.

Made in a 5-nanometer design, with 20 billion transistors and 100GB/s of unified memory bandwidth is meant to increase performance over M1. It has the same M1 8 core design with 4 high-efficiency cores and 4 high-performance ones.

All CPU and GPU cores are faster than their M1 equivalents and Apple states that when running M1 and M2 at the same power level M2 will perform 25% faster. The first version of the chip will place focus on power efficiency so if you are more on side of being a power user wait for the MAX or ULTRA version of M2.

Tech details of M2

M2 system on a chip like its predecessor M1 combines both CPU and GPU on a single chip with shared memory in order to increase performance compared to systems that have separate CPU and GPU. M2 so far has been only announced for MacBook Air and the 13-inch MacBook Pro that suppose to hit the market somewhere around July this year. Of course, we expect that M2 is included in future iPad series or Mac Mini series as well.

• CPU Cores: 8
• GPU Cores: Up to 10
• Unified Memory: Up to 24 GB
• Neural Engine Cores: 16
• Number of Transistors: 20 billion
• Process: Second Generation 5nm

The new thing from Mozilla is not a browser, it is a VPN!

Besides Firefox, Mozilla offers now Firefox Relay, an app helping you to mask your email and phone number, and a new Mozilla VPN.

Mozilla has recently announced a new subscription model that will let you use all products together for $6.99 per month. Although this is a little more expensive than the competition that goes around for $5 per month note that with this subscription you are having access to all services, not just VPN.

VPN will not only hide your IP address but will also make sure websites cannot access your real location and it encrypts all of your network activity. Relay will give you protection against spam, serving as a shield for your email and limiting spammers from access to your real email address and phone number. With Mozilla subscription will let you use both services.

In previous versions of Windows changing the system, the font was a pretty straightforward process, but it seems Microsoft did not want this feature to keep for whatever reason and there is no option as of the time of the writing of this article to do it in standard options in Windows 10. But do not worry, you are still able to customize your Windows and choose which font would you like to see inside it in all of its dialogs. You can choose whichever font you desire, the only prerequisite is it to be installed on your system. This guide will require you to change values in the registry of Windows itself so please follow step-by-step instructions and always make a backup of the registry before changing it in order to prevent some permanent Windows issues. All of that being said, let's start.

Setting new font

First thing is to open notepad, in the notepad paste the next block of code:

Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts] "Segoe UI (TrueType)"="" "Segoe UI Bold (TrueType)"="" "Segoe UI Bold Italic (TrueType)"="" "Segoe UI Italic (TrueType)"="" "Segoe UI Light (TrueType)"="" "Segoe UI Semibold (TrueType)"="" "Segoe UI Symbol (TrueType)"="" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes] "Segoe UI"="NEW_FONT"

Where in "Segoe UI"="NEW_FONT" instead of NEW_FONT you need to write the exact name of the font that you wish to use as a system font. Once you have replaced the default system font with your desired one, go to File and save as, from file type drop-down menu, choose all files and save this file as .REG type giving it whatever name you wish. When the file is saved, close notepad, right-click on the saved file and choose the merge option. Confirm with YES and click on OK. Reboot your system and your Windows will now use the font of your choice as its default system font.

Restoring default font

If you wish to return the old default system font as it was, follow the same steps but in your notepad paste this code:

Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts] "Segoe UI (TrueType)"="segoeui.ttf" "Segoe UI Black (TrueType)"="seguibl.ttf" "Segoe UI Black Italic (TrueType)"="seguibli.ttf" "Segoe UI Bold (TrueType)"="segoeuib.ttf" "Segoe UI Bold Italic (TrueType)"="segoeuiz.ttf" "Segoe UI Emoji (TrueType)"="seguiemj.ttf" "Segoe UI Historic (TrueType)"="seguihis.ttf" "Segoe UI Italic (TrueType)"="segoeuii.ttf" "Segoe UI Light (TrueType)"="segoeuil.ttf" "Segoe UI Light Italic (TrueType)"="seguili.ttf" "Segoe UI Semibold (TrueType)"="seguisb.ttf" "Segoe UI Semibold Italic (TrueType)"="seguisbi.ttf" "Segoe UI Semilight (TrueType)"="segoeuisl.ttf" "Segoe UI Semilight Italic (TrueType)"="seguisli.ttf" "Segoe UI Symbol (TrueType)"="seguisym.ttf" "Segoe MDL2 Assets (TrueType)"="segmdl2.ttf" "Segoe Print (TrueType)"="segoepr.ttf" "Segoe Print Bold (TrueType)"="segoeprb.ttf" "Segoe Script (TrueType)"="segoesc.ttf" "Segoe Script Bold (TrueType)"="segoescb.ttf" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes] "Segoe UI"=-

Reboot your system and your Windows will now revert the font of your choice as its default system font.

As of late, users have been reporting about getting an error saying, SAFE_OS phase error during Replicate_OC operation when they tried to upgrade their Windows 7 or Windows 8.1 computers to Windows 10. Although the error code in this problem could vary, in this situation, it states:

0xC1900101 – 0x20017, The installation failed in the SAFE_OS phase error during Replicate_OC operation

To fix this issue, you need to follow the given options below. But before you do, you need to create a System Restore point first so that if anything goes wrong, you can always undo the changes you’ve made.

Option 1 – Try to change the Windows 10 installation

According to security experts, one of the main causes of this error is the KB3064209Windows Update. This particular update is the one responsible for updating the CPU Microcode for processors made by Intel. Thus, if you don’t use an Intel processor, you can skip this option and proceed to the next one. However, if you use Intel, make sure to follow the instructions in this option carefully. Take note that in this solution, C: partition is referred to as the OS Partition while H: partition is referred to as the USB Pen Drive.

• First, you need to download the Windows 10 ISO from the Windows 10 Media Creation tool and then copy its contents to the Pen Drive H.
• Next, tap the Win + X keys and click on the Command Prompt (Admin0 option. If a User Account Control appears, simply click Yes.
• After opening Command Prompt, type the following command:

dism /Mount-Image /ImageFile:H:sourcesboot.wim /index:1 /MountDir:C:UsersUserDesktopmount

• Now navigate to the following path in the Windows File Explorer:

C:UsersUserDesktopmountWindowsSystem32mcupdate_GenuineIntel.dll

• From there, right-click on the file named “mcupdate_GenuineIntel.dll and click on Properties.
• Next, go to the Security tab and click on Advanced. In the Advanced section, change the Owner to your User Account and click OK.
• And then back to the Security tab, click on the Edit button and check on Full control to make sure that your User Account has all the privileges.
• Now click on Apply and then OK.
• After that, delete the file you saw earlier which is named mcupdate_Genuine.dll.
• Then close all the Windows File Explorer instances and go back to the Command Prompt window and unmounts the image you mounted before by typing the following command:

dism /Unmount-Image /MountDir:C:UsersUserDesktopmount /commit

• Afterward, repeat the steps from mounting up until here for these files:
  • wim /index:2
  • wim /index:1
  • wim /index:2
• Now delete the mount folder and remove the USB Pen Drive and then boot with the installer.

Option 2 – Try to perform a Disk Cleanup

Chances are, some unnecessary files in your computer might be interrupting the installation process which explains why you’re getting SAFE_OS phase error during Replicate_OC operation instead so you need to perform a Disk Cleanup in order to fix the problem.

Option 3 – Try updating all your drivers

Every now and then, drivers get corrupted or outdated so it’s no surprise that they conflict with the operating system and cause errors like the SAFE_OS phase error during the Replicate_OC operation. To fix the problem, you need to update all your drivers. Follow the steps below to update your drivers.

• Tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. If you see a red or yellow sign that shows up against the driver, right-click on the driver’s name and select “Update Driver Software” or “Uninstall”. And if you find any “Unknown device”, you need to update it as well.
• Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
• Restart your PC.

Note: You also have the option to go directly to the website of your graphics card manufacturer and check if there’s a new update – if there is, download it.

Option 4 – Try to update your system’s BIOS

Aside from outdated drivers, outdated BIOS could also be the reason why you’re getting the SAFE_OS phase error during Replicate_OC operation which is why you need to update your system’s BIOS in order to resolve the issue.

Option 5 – Try checking the Windows Services status

• In the Cortana search box, search for “Services” and then click on the Services icon.
• After that, the Services utility will be opened in a new window.
• Next, look for the following services:
  • BITS (Background Intelligent Transfer Service)
  • Windows Update Service
  • Cryptographic Service
• Then right-click on each one of the services and click on Properties. From there, select Automatic from the drop-down of the Startup Type menu.
• Now click on OK for each one of them and restart your PC to apply the changes made.

Option 6 – Try to check the RAM modules

There are many times when all the components of the RAM weren’t able to be used by the computer so you need to check the RAM modules.

• You need to first turn off your PC and then take out your RAM physically.
• Next, clean it with a soft cloth and blow some air into the RAM slot in the motherboard.
• After that, put your RAM back in the same slot.
• Then try updating your computer system again.

As you know, “JPEG” is one of the commonly used formats for image files which is a compression of digital images. It is one of the topmost used file formats by mobile phones and digital cameras and usually achieves a 10:1 compression with little visible loss in the quality of the image. There are tons of cases as of late, most particularly after the latest Windows 10 update where users were not able to open JPEG files on their PCs. Every time they try to open any JPEG file, they either get an error or nothing happens at all. This issue could be due to the default handler application for JPEG applications not being set or there could be some third-party image viewer not working properly. To fix this issue with JPEG files, refer to the troubleshooting options below.

Option 1 – Try to change the file type association

You need to check if the file type association of the JPEG files are correctly set or not since there are tons of third party programs that change the file type association automatically to themselves without your permission the instant they are installed and so if any of these third-party programs are broken, then naturally, your JPEG files won’t really open. That’s why you can try changing the setting to the default photo viewer instead of the third-party one. To do so, follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Then type in “control panel” in the field and hit Enter to open the Control Panel.
• After opening Control Panel, click on the Programs category and select the “Default Programs” option from the menu.
• Next, select the second option “Associate a file type or protocol with a program” and then select the “Choose default apps by file type” option.
• After that, click on the .jpg file extension and choose the option from the pop-up.
• Now restart your PC to refresh all your programs and then see if it has fixed the problem or not.

Option 2 – Try to update your computer

Microsoft frequently releases updates to target bugs and improve users’ experience. And this particular error where JPEG files won’t open is already acknowledged by Microsoft so you need to make sure that your Windows 10 PC is updated to the latest released update and that there are no pending updates.

• Tap the Win + S keys to open Search and then type in “update” in the field and open the system setting from the search results.
• After that, check for updates and then download and install them if needed.
• Now restart your PC once the update is done and check if you can now open JPEG files.

Option 3 – Try to reset the Photos app via Settings

Resetting the Photos app could also help you in fixing the problem. Note that this option will reset all the configurations and your data associated with your Photos and makes the application go into a state when you first started using it and that this option will fix any discrepancies that your application might be experiencing right now.

• Tap the Win + S keys to open the search bar.
• Then type in “settings” in the field to open the Settings application.
• After opening Settings, click the “Apps” category.
• From there, a list of applications installed on your computer will appear.
• Navigate through these applications until you find the Photos app and then click on the Advanced options.
• Afterward, click the Reset button that appears on the next screen. Then a new pop-up comes up and will warn you that all the preferences, as well as sign-in information, will be lost. Click on “Reset” anyway to proceed in resetting the Photos app.
• Restart your PC once the reset is done.

Option 4 – Try to reinstall the Photos app

Before you start using other third-party image viewers just yet, you can try to reinstall the Photos app first. Thus, if there is something wrong with it, it will instantly get fixed right after it reinstalls. Just take note that this option requires administrative privileges so you need to be logged in as an administrator.

• The first thing you have to do is tap the Windows + S keys and type in “PowerShell”.
• Next, right-click on the file and click on the “Run as administrator” option from the context menu.
• Once PowerShell is opened, execute this command: get-appxpackage *Microsoft.Windows.Photos* | remove-appxpackage
• The command you just entered will remove the Photos app. After the process is done, go to the Microsoft Store and look for Microsoft Photos then download and install it again.

Manually cleaning your PC registry may be the worst or best thing you ever decide to do. Registry keys that lie around on your computer, unused, can cause your computer to lag. This can end up in your computer not being able to load the easiest of programs and being slow at loading anything, let alone something that would take up a decent amount of memory. If your computer has slowed to almost an absolute stop, it is most probably the registry’s fault and the only option then is to clean it. You can get programs to do this for you, but they can be riddled with inaccuracies and viruses that could harm your computer even more. This is why some people choose to manually edit their computer. However, this is not without its flaws.

Registry Keys

Registry keys tend to have really long names. These names will be full of numbers and hyphens and will most likely give you no indication of what they do. Even some computer experts find it hard to understand what every computer’s registry keys do. This can make it very hard to see which ones are causing the problem; and if you don’t know what’s causing the problem, then there is no way you will be able to fix it. Some registry keys will be completely menial in what they do but some could be vital to even allow Windows to work on your computer.

Manual Registry Repair

Registry keys can also cause huge problems if you manually delete the wrong one. A lot of registry cleaners have the option to revive a key that they have deleted on you, which means that fixing an error that they made would be easy enough to do. However, when you manually delete registry keys, it will be an awful lot harder to get them back to work again afterward. This can cause your computer many problems and if you delete even one wrong key it is possible your computer will not even start. With the horrid naming system they have as well, it makes it very hard to determine what is important and what is not, which means it is all too likely that you will delete something important. However, those are the risks you have to take when you are cleaning out your registry. A registry cleaner has the same likelihood of messing with your computer and deleting something wrong that you have, so it is the same either way however a registry cleaner will do it with less hassle. But, some people say that if you do it yourself, it’s more likely to be right; that is why they prefer to do it manually and that is alright.

Conclusion

So, if you are manually deleting your registry keys that are unused, you’ll have to use a program that comes with Windows known as ‘regedit.exe’ which is incredibly difficult to use but may just be worth the hassle in the end. So, you don’t really need to put up with a slow computer, but be careful when messing with your registry manually!

Microsoft office has two major packages, an online one, and an offline version. The online version of the course is Office 365 that requires a monthly subscription and it is always regularly updated and maintained. Another version is more of a typical old school application, install it and use it, no constant internet connection is required and no monthly subscription is required, buy once and use it. The last version of buying it once and use it was Office 2019 and after two years we are going to receive a new version soon. Microsoft has set its release date for October 5^th of this year and as always it will feature the current latest version of office applications and one-time purchase. The new office will support dark mode and other improvements tied to the new Windows 11 and some specific features tied to Office itself.

The “Unknown Hard” error that keeps on appearing in Windows 10 can put users in an unpleasant situation. This kind of error leads to the freezing of the taskbar, blackening of the screen, and sudden disappearance of the icons on the Desktop. And each time you try to open Windows, the system will only give you an error message saying that it’s a critical error and some applications like Start and Cortana won’t work. Upon analysis, it seems that the “sihost.exe” is not responding and that it is the one that’s causing the c000021a Unknown Hard error to pop up. Sihost.exe files represent the Shell Infrastructure Host which is an essential component in the Windows operating system. The Windows Shell Infrastructure Host is primarily responsible for handling some graphical elements of the operating system interface such as the Start menu and the taskbar transparency. And so if the Shell Infrastructure or Sihost.exe has stopped, has been removed, or corrupted, you will most likely have issues with the overall functionality of the Windows operating system and you’ll get the Unknown Hard error In addition, the ctfmom.exe Unknown Hard error may also occur due to incompatible drivers installed on your PC. Ctfmom is a process that identifies inputs such as handwriting, languages, and many more. It’s the one that controls the functions of background behavior. To resolve this issue, you need to first try to identify which application is the one that’s running the sihost.exe file. And if needed, you need to either update or reinstall or completely uninstall the problematic application.

Option 1 – Try to run the System File Checker

The SFC Scan or System File Checker, us a built-in utility in Microsoft Windows that can be found in the C:\Windows\System32 folder. This tool allows users to scan and restore any corrupted system files in Windows that might be causing the Unknown Hard error to appear. Before you use this tool, make sure to find out whether the sihost.exe on your computer is a Trojan that you have to remove or if it’s a file that belongs to a trusted Windows application. Once you have that sorted out, follow the steps below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

Option 2 – Try to use System Restore

You can also try using System Restore. This is one of the ways you can use it to back up your PC. Since restore points are created automatically each week by System Restore, you can use System Restore to restore your computer back to an earlier good point in time.

Option 3 – Try to troubleshoot the error in a Clean Boot State

Putting your PC in a Clean Boot state can help you diagnose and troubleshoot the issues in your system. During this state, you can start the system with a minimum number of drivers and startup programs that will surely help you in isolating the root cause of the Unknown Hard Error.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” checkbox and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” checkbox.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)

After putting your PC in a Clean Boot State, try creating a system restore point and see if the problem still occurs. Clean Boot troubleshooting is designed to help you isolate the problem. For you to execute a clean boot troubleshooting, you must do a couple of actions (the steps are given above) and then restart your PC after every action. You might have to disable one third-party app after the other to really isolate the issue. And once you’ve narrowed down the problem, you can either disable the third-party app that’s causing the problem or remove it. Note that you must switch your PC back into the Normal Startup mode after you’re done troubleshooting the problem. Here’s how you can do it:

• From the “Start” menu, go to System Configuration.
• After that, switch to the General tab and click the option for “Normal Startup”.
• Next, go to the Services tab and clear the checkbox for “Hide all Microsoft services”.
• Then find and click “Enable all” and if prompted, you have to confirm.
• Afterward, go to the Task Manager and enable all the Startup programs and confirm the action.
• Restart your PC when prompted.

What Is Installation Error 1628?

Installation Error 1628 is, as the name suggests, an installation error. When it occurs, a generic 1628 message is displayed to the user. When this message appears, it is either a problem with the install files or an issue with the InstallShield.

Solution

Error Causes

Installation Error 1628 is caused because every Windows-based program or application has been designed that such that it has to be installed on the computer for use. This installation process is important because it not only moves files to the appropriate location on one’s hard drive but also because the process creates registry entries in Windows System files. A vast majority of these programs and applications have a built-in tool that’s responsible for aptly performing this installation. This built-in tool is the InstallShield. This establishes that when this error occurs, it is either because of some unforeseen issue that occurred during the installation process or because of some problem with the InstallShield.

Further Information and Manual Repair

In order to keep this error from occurring in the future, some recommendations are outlined below.

• Check the installation disc and determine if there are any smudges, scratches, or fingerprints on it. If the system is unable to read data from the disc, Installation Error 1628 will be generated. In order to ensure that the Installation Disc is clean, use a microfiber cloth. Dampen it lightly with water and clean the disc. Wipe the inside of the disc lightly in an outward direction, making sure that it is not wiped in a circular pattern. Try to reinstall the application or program after cleaning the disc. The issue should be resolved. However, if it persists, some problems may be with the InstallShield.
• The alternative solution is to repair the InstallShield and the procedure goes as follows.

1. Stop InstallShield’s running process. It may have been crashed and simply needs to be restarted. Now access task manager. Press Ctrl+Alt+Del and the task manager will open. Now go to the processes tab and disable ‘idriver.exe’ and ‘msiexec.exe’ from here.
2. Now go to ‘C: Program Files/Common Files’. Here you will find the ‘InstallShield’ folder. Select ‘rename’ and modify the folder name to ‘InstallShield1’. Confirm rename and start the installation process again. Now Windows will try to re-install any InstallShield files one needs.
3. If the error persists after renaming the InstallShield folder, download the Windows Installer from Microsoft’s website. This file will determine whether or not your version is valid. Old versions often have bugs that cause problems. Your system is now ready to be used.

Recently, a number of users reported that they were not able to run PLEX and other similar streaming services ever since a Windows Update was automatically installed in the system. The error in these streaming services has something to do with a missing Mfplat.dll DLL file from the Windows Media Feature Pack. On the other hand, some users also reported that the mfplat.dll error occurred on several games as well which used the Media Feature Pack. Usually, the mfplat.dll error is caused by the missing Media Feature Pack in Windows 10. Although most of the time the Media Feature Pack is installed by the application that needs it or through Windows Update automatically, there are just certain installers that do not have it. It could be that the Media Playback service was disabled by a particular Windows Update. Aside from that, the error might be because your computer is using Windows 10 N – a Windows 10 version that does not include the Media Feature Pack by default. Whatever the cause may be, you can troubleshoot the problem with the help of the options given below. But before you go on, keep in mind that downloading the missing DLL file and copying it to the folder of the program where you encounter the error won’t really help and will only make things even more complicated.

Option 1 – Install the Media Feature Pack for Windows 10 N version

As mentioned, the Windows 10 N version does not come with Windows Media Player. Meaning to say, the Media Feature Pack is also not installed by default or won’t be updated by the Windows Update component. So if you are not quite sure what Windows 10 version you currently have installed, refer to these steps:

• Tap the Windows key + S and then type “about” in the search box.
• From the search results, click on the “About your PC” to open the About tab of the Settings app.
• Afterward, scroll down to the Windows specifications and check your Windows version under Edition.

Note: If you’ve determined that your computer is using the Windows 10 N version, you need to install the appropriate Media Feature Pack for your computer. How? Refer to the steps below:

• Click this link to download and install the Media Feature Pack from Microsoft’s official website.
• Upon installation, select the edition you want to install using the drop-down menu and then click on Confirm. Take note that there are few reasons why you’d want to install the older version since most streaming services like PLEX and most games usually require version 1803.
• After that, wait until the request is validated. The download should begin in a few minutes automatically.
• Once the download is completed, open the installation executable file and follow the next on-screen instructions to install the Media Feature Pack on your computer.
• Restart your computer. After your computer has rebooted, open the application where you’re getting the mfplat.dll missing error and then check if the problem is now fixed.

Option 2 – Enable Media Playback via Command Prompt

If you encounter the mfplat.dll missing error when you attempt to run PLEX or other similar streaming service and you’ve already verified that the Media Feature Pack is indeed installed, you might want to try enabling it using an elevated Command Prompt. There are cases when a particular Windows Update ends up disabling the feature and creates the grounds which results in the mfplat.dll missing error. Thus, you can have to enable the feature via Command Prompt.

• Tap the Win + R keys to open the Run dialog box.
• Then type “cmd” in the field and hit Enter to open an elevated Command Prompt.
• Next, click on Yes if a User Account Control prompt pops up.
• After opening Command Prompt, copy and paste the following command and hit Enter to execute it:

dism /online /enable-feature /featurename:MediaPlayback

• Close Command Prompt and then open the app once again to check if the problem is now fixed.

Option 3 – Try extracting a copy of the mfplat.dll file from the windows.old directory

If you encounter the error shortly after you just upgraded to Windows 10 from an older version, the best thing you can do to resolve the problem is to use windows.old directory to fetch an old copy of the mfplat.dll file. To do so, follow the steps below.

• Go to the Windows drive and then look for the windows.old directory where it preserves a copy of your old operating system as well as associated files in case something goes out of hand during the upgrade process.
• After that, open the windows.old folder and then go to the syswow64 folder.
• Next, from the syswow64 folder, copy the mfplat.dll file and paste it to C: windows syswow64.
• Restart your computer and check if the error is now resolved or not.
