How to Repair Missing MSVCR100.dll Error

So, you just made some popcorns, dimmed light, relaxed in from of the TV, pressed play on your application and Blu-ray drive can not read your movie. Your movie night failed sadly, but there is hope and in this article, we are going to explore and offer you solutions on what to do when something like this happens so you do not miss another movie night and some hard-earned relaxation. Please note that in this article we are assuming that you are using a Blu-ray player on your PC, so some of the solutions presented are meant only for this case. So the first thing that you are supposed to do is to check the disc itself. You can turn the disc around and visually check the disc for fingerprints and scratches which can be fatal for disc playing, alternatively, you can try to play the same disc on another device and if it fails there also it is not the disc, it is your drive. So if it is no issue with the disc let's see that seems to be a problem with the drive. The common thing that could stop disc reading are cables, check all connections and cables in the back of your device to be sure that everything is plugged in correctly and nicely. After checking cables if the issue persists lens cleaning is the next step. Over time lens from the Blu-ray, the device becomes dirty and dust accumulates on it, there are special cleaning discs on market made especially for this purpose, to clean the dirty lens of optical devices. If you have one put it in and clean your lens. After lens cleaning with a specialty disc, a good idea would be to use compressed air in a can to reduce the dust inside so no excess dust will accumulate quickly again on the lens itself.

So the device is cleaned and checked and still no disc playing?

Update firmware first. In order to accomplish this visit your device manufacturer's website and follow instructions there on how to upgrade firmware. If this did not helped also update or reinstall device drivers. Go to device manager and update drivers for your device by right-clicking on it and choosing update driver. If none of the things helped, go to command prompt as administrator and type in SFC /scannow, leave the process to finish, and reboot.

One of the biggest annoyances in Windows 10 is that it’s upgrading from one version to another. Although these upgrades are necessary to fix some bugs or improve user experience, some of them actually bring bugs into the computers instead. And in one of the recent Windows 10 updates, a lot of issues were found especially for users who use Remote Desktop on a daily basis. The error stacks up as Windows 10 Remote Desktop Protocol client is not working or won’t connect and can’t find the computer HOSTNAME generally. Based on the reports by users who experienced this issue, there are two cases around it:

1. Users who try to reach a specific website or folder on the network

Some users encounter this error when they try to run the Network Troubleshooter. Even when they add the server name inside it, it still won’t identify the problem, and unpredictably, the driver seems to appear and disappear every now and then. And even after connecting, the network commands don’t work at all. This is really troublesome for users who have lots of PCs and all the other systems do not appear on the network.

2. Remote Desktop isn’t able to find the computer HOSTNAME

Some other users reported that the error appeared when they use the classic remote desktop software. It keeps on failing and throwing the error message, “Remote Desktop can’t find the computer “HOSTNAME”. If this is the same scenario you are having, it means that “HOSTNAME” does not belong to the specified network. So you need to verify the computer name and domain where you are trying to connect to. There are times when it used to work after some users tried connecting to the domain a couple of times. However, when users try to use the UWP version of Remote Desktop, it seems to connect most of the time. This kind of problem is definitely a DNS issue. It could be that there are two different records on the DNS server which is why it connects and other times it doesn’t. When it is able to resolve the correct address, the drives connect to the PC however, after a couple of minutes, they will suddenly go missing. Using “nslookup” for the hostname, multiple times, you can check this and see if you’ll get identical results all the time.

nslookup [–SubCommand …] [{ComputerToFind| [–Server]}]

If you’ve determined that the drives disappear each time, you may have to change the DNS server or ask your admin to resolve the problem for you. Alternatively, you can also check out another option that has worked for a lot of users. This second option is disabling the IPv6 on the network adapter. In case you don’t know, Windows 10 prefers IPv6 over IPv4 so if you now have issues using IPv6 to connect to the servers, you can change your computer’s settings so that it’ll only use IPv4 instead of IPv6. To do so, follow these instructions:

• Open Settings > Network and Internet > Ethernet > Change Adapter options.
• From there, right-click on the adapter for where you want to disable it and then select Properties.
• Next, look for the checkbox labeled, “Internet Protocol Version 6 (TCP/IPv6)” then uncheck it.
• Now click on OK and restart your PC to save the changes made.

Microsoft has been bringing new lock-screen features with every iterative feature release of Windows 10 in order to improve user experience. However, Windows 10 users have different opinions regarding it. Some users are pleased with it while some users simply do not like it. So if you are one of the users who seem to not approve of this feature, read on as this post will be about enabling or disabling the Console Mode sign-in feature in Windows 10. Before you proceed, take note that you will not be able to use your mouse pointer in this Consol Mode login screen and you can only use your keyboard to navigate around various options. You might also want to create a System Restore point just in case. To enable or disable the Console Mode sign-in in your Windows 10 computer, refer to the given steps below. Step 1: Tap the Win + R keys to open the Run dialog box. Step 2: Then type in “Regedit” in the field and tap Enter to open the Registry Editor. Step 3: Next, navigate to the following registry path:

ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionAuthenticationLogonUITestHooks

Step 4: From there, look for a DWORD named “ConsoleMode”. If you don’t see this DWORD, you can just create a new DWORD and name it as “ConsoleMode” and make sure that its base is set to Hexadecimal. Step 5: After that, double click on ConsoleMode and change its value to “0” to disable it and “1” to enable it. Step 6: Now restart your computer to apply the changes made. Like pointed out, you can only use your keyboard when you’re in the Console Mode login window or screen. You can just use the ESC button to go back to the menu while you can utilize the arrow keys so you can go through the options that are mostly vertically arranged and the Enter key to select an option. In the Console Mode, sign-in using the Passwords and PINs worked efficiently.

Shortcut virus is an easily spreadable and annoying combination of Worm and Trojan that hides all of your files and folders and then replaces them with shortcuts that look identical to replaced files and folders. Once disguised it will wait patiently for a user's click and once that happens it will replicate itself and further infect the system. This rapid spread can lead to stolen personal data, some system hick-ups, and other system-related issues. This malware mainly affects physical file transfer devices like for example and most USB drives, hard drives, and SD memory cards and it can easily transfer itself to the computer. The advantage of this shortcut virus comparing it to others is that it is mostly undetected by a vast variety of antivirus software. So running just anti-virus software maybe not be enough to remove it from your system. Luckily for all unfortunate users that have caught this annoyance, it can be easily removed fully manually in a short time.

How to Remove Virus from USB and other removable media

Firstly plugin USB, SD, or removable drive. The infection will transfer to your computer when the infected drive is plugged in so before we go to clean the computer itself, clean each removable drive that you have. Also know that infection will spread from computers into removable devices as well if it is not cleaned. Open the File Explorer and remember under which letter is removable drive registered. Open Command prompt but with administrator privileges and go to infected rive by typing its letter followed with “:” (for example D:) and press ENTER Once you have successfully gone to infected drive type in command prompt: Attrib -s -r -h /s /d *.* This will unlock all original files back into removable storage, next copy all files to your computer, and format the removable drive. Once the format is complete, unplug the removable device. Continue to clean all devices with the same method.

How to Permanently Remove a Shortcut Virus from Your PC

Now once we have cleaned all removable devices it is time to fully clean the PC Firstly open the task manager ( CTRL + SHIFT + ESC ), in the process tab find wscript.exe or wscript.vbs, right-click on it (or both if present), and select End Task. Now close the task manager and press Start. Inside start typing in registry editor to search for it and once found open it. Find the following key inside the registry editor: HKEY_CURRENT_USER/Software/Microsoft/Windows/CurrentVersion/Run In the right panel, look for any strange-looking key names, such as odwcamszas, WXCKYz, OUzzckky, etc. For each one, run a Google search to see if it's related to shortcut viruses. If any returns a positive match, right-click on them and select Delete. !!! Accidentally deleting an important key can cause Windows to become unstable, so double-check everything !!!. Close the Registry Editor Now press ⊞ WINDOWS + R to open the run dialog and type in it Msconfig followed by ENTER. Once the System Configuration window opens go to the Startup tab. In the Startup tab, look for any strange-looking .EXE or .VBS programs, select each one and click Disable. Close the Window. Once again open the run dialog and type inside %TEMP% and press ENTER in order to open the Windows temp folder. Inside this folder delete everything. Next in the File explorer go to C:\Users\[username]\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup Look for any strange-looking .EXE or .VBS files and delete them.

If this unfortunate COVID-19 worldwide pandemic has managed to teach us, I would argue it is that our health is the most important thing. So in that spirit, we will continue in this article reviewing some of the best fitness trackers that can be found in the time of writing this article in 2021. Now the market for fitness trackers is not small by any means and offerings are also not small, from no-name manufacturers costing only a few bucks to more serious one’s going slightly over 100 USD there is a fitness tracker for everyone. In this particular article, we will not focus on cheap few dollars no-name ones, instead, we will be offering top ones in the field among some in the middle range simply because we can stand behind them considering quality and precision.

Fitbit Charge 4 fitness and activity tracker

Fitbit is not a pioneer company in the world of fitness trackers and it shows. Charge 4 model offers maybe the best quality, performance, and features for its price. It stands out with implemented GPS meaning that you will need your phone for tracking workouts. It also offers step tracking, sleep tracking, automatic workout-tracking, active zone minutes, etc. It weighs 30g and has 1 inch grayscale OLED. Battery life is said to hold up to 4 days if you use built-in GPS regularly, if you decide to use GPS constantly device will last only 5 hours. Without GPS it can last up to 7 days and it is water-resistant and waterproof up to 50 meters.

Amazfit Band 5

Amazon’s offering of fitness tracker is aimed at beginners and as such, it is lacking some advanced features including an automated working tracker or GPS, also the model does not have replaceable bands so customization is not an option. It does however offer activity and sleep tracking, heart rate monitoring and it is the only model that integrates with Alexa. The manufacturer states that the battery can last up to 15 days depending on usage which places Amazfit Band 5 as a device that has a longer life of use. The device itself is packed with a 1.1-inch color OLED and it weights 12g. It is splash-resistant, not water-resistant.

Xiaomi Mi Band 6

Xiaomi tracker is the best budget version on this list including in it 30 sport modes like running, cycling, yoga, swimming, and more. Battery life is not bad also packing up to 14 days of life but only if the device is not used constantly. It has activity and sleep tracking, a heart rate monitor, sleep tracking, customizable replicable bands and it is water-resistant up to 50m. It comes in a 1.56 inch AMOLED color display and it weighs 63g. The device also has menstrual health tracking making it a great device for women.

Samsung Galaxy Fit 2 fitness tracker

Now we are getting into serious and little more expensive ones. Galaxy Fit 2 is among the top-notch trackers currently on the market. It of course can work along with Samsung’s smartwatches and mobile phones. Packed in the military-grade 1.1-inch casing with color AMOLED and weighing 91g with battery life up to 21 days and water resistance up to 50m this bracelet is an absolute beast. It comes packed with features from standard sleep tracking to automated workout-tracking but it also has a connection to Samsung’s Health mobile app to choose from over 90 workouts, it monitors heart rate and stress levels making it really one of the complete solutions for serious fitness enthusiasts.

Garmin Vivosmart 4 fitness tracker

Last on our list is Garmin vivosmart 4. The device itself is not very impressive, 7 days battery life with 0.7 inch OLED display and 17g weight packed with 50m water resistance is nothing spectacular, Samsung’s model is packing better hardware and way more battery life but all of the mentioned devices fall flat if we compare software to Garvin. Garvin’s Vivosmart 4 software is best on the list, it keeps track of your steps, sleep, calories burned, floors climbed, various exercises, and heart rate as standard features but you'll have advanced sleep tracking with REM sleep. It can also gauge blood oxygen saturation levels during the night with its wrist-based Pulse Ox sensor. In addition, a relaxation breathing timer complements the all-day stress tracking feature. Lastly, the "Body Battery" monitor helps optimize your daily activities based on your energy levels making it truly the only complete tracking solution on this list.

In today's world setting up a LAN network or internet connection is no longer a daunting task that will require having a bachelor's degree in computer science nor a specialized technician. But even in the present-day environment issues and problems can occur. One of these problems is detecting or running a network at a slower 100MB speed instead of 1GB. Troubleshooting of this nature is somewhat more complex than your typical troubleshooting issue because several things including hardware could be involved in this particular problem but do not worry, we are here to back you up and guide you Setting up a home or small office network no longer requires a specialist technician to constantly monitor and optimize the LAN routers and connected PCs. As Windows networking has improved and new features have become available on the hardware, configuring a 1GB network should be as simple as connecting the LAN to a router that came with this capability. If however the network’s rated speed only gives 100MB, troubleshooting the issue is more complex. To find the problem, you’ll need to check the hardware devices, cable connections, and the software you are using to connect and manage the network.

Hardware checks

1. Check both connection jacks to see if it has any loose or frayed wires. If any of the wires are loose, it can be the cause of the performance issue. You should replace the cable if you discover damage to the connectors.
2. Inspect the entire length of the cable and check if the harness shows any clear signs of damage. A bent or damaged cable can reduce the amount of information it’s capable of transferring between the PC and LAN router. If you find any damage to the cable, replace it to restore your network speed.
3. Is the cable capable of transferring 1GB speeds? Different network cables support different network speeds. A Cat-5 cable will only provide 100MB transfers, while a Cat-5e or Cat-6 can support up to 10GB transfers. Check the cable’s labels to make sure you are using a Cat-5e or higher-rated data cable.

Now when the hardware issue is out of the way we can focus a little more on the software part.

Let's try the first easy solution, run Windows built-in troubleshooter

1. Click the Windows button and type Control Panel. Then select the top result.
2. If your Control Panel shows the Category View, change it to display Small Icons instead.
3. From the list of available applications, select Network and Sharing Center.
4. In your Network and Sharing Center, you can see the active network, set up a new network connection, troubleshoot problems, or change your adapter settings. Before making changes to your device properties, you can let Windows run a troubleshooter on your adapters to see if it can automatically fix your connection issues.
5. Click on Troubleshoot Problems from the Change Your Network Settings section.
6. In the Troubleshooter Application, scroll down and find the Network Adapter option.
7. Click on Run Troubleshooter to let Windows check your network adapter’s configuration for any issues.
8. Select the Ethernet Adapter you’re currently using from the list and click Next to proceed.
9. Wait for the process to complete and check the results. If Windows detects any issues, it will recommend a fix. However, if the configuration of your network adapters does not have any problems, you’ll see a message that Windows couldn’t detect any problems.
10. If there are any issues with the cable, the troubleshooter will detect the connection issue and request you replace the cable and connect it to your PC.
11. It can occur that even after inspecting the cable and you didn’t find any visible damage on the housing or connectors, it could still be faulty. Replace the cable with a new one and rerun the troubleshooter to see if the cable is working as required.

If the troubleshooter finished and you received a Windows Couldn’t Detect Any Issues result, you’ll need to verify your adapter’s speed settings.

1. In your Network and Sharing Center, select the Change Adapter Settings option from the left menu.
2. On the list of adapters, choose the one you’re using and click the Right Mouse Button to open the context menu.
3. Select Properties from the Context Menu to access your adapter’s settings.
4. On the Ethernet Properties window, you can enable or disable different features and install additional protocols. To change the device settings, click on Configure to continue.
5. This will open the Device Controller Properties window where you can check the status, make changes to the settings, find out information about the driver, or check historical events on the device. Select the Advanced tab to access the device settings.
6. On the Advanced tab, locate the Speed and Duplex setting.
7. The Auto-Negotiation option may cause network performance issues on certain Ethernet adapters and routers. The setting allows your adapter to change the speed settings according to the LAN configuration you connect to your PC. If you connect to different LAN networks regularly with different speeds, it can occur that the setting doesn’t update from 100MB to 1GB while switching.
8. Change the Value to match the network speed of the LAN you’re connecting to your PC and use the manual speed setting.
9. Click OK to apply the setting and test your network performance. If your adapter doesn’t have the 1GB setting available but you know the rating should go up to that speed, it could indicate that you aren’t using the right driver for the device.

If you don’t have the setting available or the device still only provides 100MB speeds after changing the Speed setting to a manual value, you may have to update the driver for the device.

1. On the Ethernet Properties Window, once again click on Configure to access the Device Properties Window. Then select the Driver Tab to access your driver details.
2. Select Update Driver from the available options.
3. On the Update Driver window, select the option to let Windows Search Automatically for Updated Driver Software.
4. Windows will connect to the internet and search for the latest drivers online. If a newer driver exists, Windows will download and install the driver for you. If you’re using the latest driver, Windows will inform you that no updated drivers are available.

‘R6025 pure virtual function call’ is a runtime error that occurs suddenly on the screen and disrupts the program being run prior to it. This error display indicates that the program has been corrupted. R6025 runtime error usually occurs with the Visual C++ framework.

Solution

Error Causes

This error occurs when the C++ program crashes which is usually because of the malfunctioning or missing of the device driver or incomplete device driver files. It happens because your application indirectly calls a pure virtual member function in a context where a call to the function is invalid. Most of the time, the compiler detects it and reports it as an error when building the application. R6025 error is usually detected at run time.

Further Information and Manual Repair

To fix the R6025 pure virtual function call error, you need to find the call to the pure virtual function. After you find the call, you need to rewrite the code so that it is not called again. There are 2 ways to do this:

Alternative 1

One way to fix the R6025 pure virtual function call is to replace the function with an implementation that calls the Windows API function DebugBreak. The DebugBreak causes a hard-coded breakpoint. Once the code stops running at this breakpoint, it is easy for you to view the call stack. By viewing the call stack you can identify the place where the function was actually called.

Alternative 2

Another quick way to find a call to a pure virtual function to fix the R6025 error is to set a breakpoint on the _purecall function that is usually found in PureVirt.c. By breaking this function you can trace the problem occurring and rewrite the call to ensure the error does not occur and the program you are trying to develop on the Visual C++ framework is easily developed. If R6025 Error is related to Windows Registry Problem Then here’s how you can fix the problem: To fix the runtime error R6025, run registry cleaner software to scan and fix all errors.  This alternative is suitable if the R6025 error is related to the Windows registry problem and where the error has occurred due to corrupted or malicious registry entries. You can download the registry cleaner repair tool for free. Run it to scan errors and then click the fix error button to repair the problem immediately.
