When you get the error information, "The Software Can Not Begin Because MSVCR100.Dll Is Missing", what this implies is that the Computer will be lacking the  MS Visual C++ 2010 libraries. The malfunction is rather frequent throughout installations. It doesn't matter the number of times you try to reinstall the program. The malfunction can happen whether you've been utilizing your pc for many years, or it's really a recent one.

Solution

Error Causes

a) Missing MSVCR100.DLL: As the problem message indicates, you get this information mainly because MSVCR100.DLL is completely missing. b) Broken MSVCR100.DLL: When the msvcr100.dll is broken, you will also get the same error, suggesting the software won't start. The thing you need to understand is the fact that MSVCR100.DLL is playing an important role in the application referred to as MS Visual C++ 2010 Redistributable Package. Without the MS Visual C++ 2010 Redistributable Package, any software that you simply make an effort to install won't start. You could possibly complete installing it by pursuing proper installation procedures, and then end up getting the "The Software Can Not Begin Because MSVCR100.Dll Is Missing" error.

Further Information and Manual Repair

If you get the "The Software Can Not Begin Because MSVCR100.Dll Is Missing" error information on an effective setup of any software, you shouldn't worry. You can really repair the issue and commence your recently installed software without any more hassle. Start by checking whether you presently use 64-bit or 32-bit Windows. Visit the start button, in case you use Winxp. Type winver. On the window that appears, click Run, subsequently push enter. Head to Start, in case you use both Win7 or Vista. Subsequently, click on the search box and type “Computer”. Right-click windows and subsequently click on Properties. Under Windows Edition, you'll find whether your Windows is 64-bit or 32-bit. Search for the correct variation of MS Visual C++ 2010 Redistributable Package, as soon as you discover whether your Windows is 64-bit or 32-bit. Down load the x86 variant of MS Visual C++ Redistributable Package if your version is 32-bit and you must obtain the x64 variant of MS Visual C++, for those who own a-64-bit version of Windows Operating System. You must never obtain MS Visual C++ 2010 Redistributable Package from third-party websites. This is because Microsoft doesn't charge a cent for the files. The files are openly and easily available on Microsoft. These files come in many different variants. Consequently, select what's suitable for your own Computer with regards to the version of Windows which you operate.

• Never pick the edition of MS Visual C++ 2010 Redistributable Package that's not compatible or appropriate to your Windows Operating System.

Make use of the release date, when installing MS Visual C++ 2010 Redistributable Package. You might also look out for Service Pack 1 and obtain it for your Windows. Service Pack 1 only ensures that you simply obtain the latest edition. As soon as you end installing the most up-to-date version of MS Visual C++ 2010 Redistributable Package as demonstrated above, reboot your computer and you'll not have to worry about getting the annoying"The Software Can Not Begin Because MSVCR100.Dll Is Missing" error message anymore.

Compare Exchange128 error – What is it

Some Windows 7 and Windows 8.1 users reported experiencing a Compare Exchange128 error when trying to upgrade to Windows 10. The error reads, “You can’t install Windows 10 because your processor doesn’t support CompareExchange128”. In order to upgrade to Windows 10 (64-bit), the CMPXCHG16B instruction must be present. If you receive this error, this mostly means that your CPU doesn’t have the CMPXCHG16B instruction.

Solution

Error Causes

The CompareExchange128 error normally occurs due to two possible reasons:

• CPU lacks CMPXCHG16b Instruction
• Old & Outdated BIOS – Even if your CPU has the CMPXCHG16b instruction, the CompareExchange128 issue can still occur if you have an older BIOS.

Further Information and Manual Repair

One main requirement to upgrade to Windows 10 is for your CPU to have the CMPXCHG16b instruction. You also need the right BIOS version to guarantee a smooth installation. See below on how to manually fix this issue.

NOTE: If you don’t feel confident using the manual methods listed below, it’s highly advisable to get help from an expert technician. If you don’t know someone, you can also use an automated tool to fix this.

Before performing any fixes, try to determine first if the cause of the error is due to your CPU lacking the CMPXCHG16b instruction. You can use a CPU Info tool that provides complete details about your processor, memory, and motherboard. If you’re looking for more in-depth information, you might also try command-line utilities. But, the safest and easiest way to check this is by simply searching online. Try using the search query: <CPU Model> CMPXCHG16b

Method 1 – Update your BIOS

This method will download the latest BIOS from your motherboard’s manufacturer. This makes sure your CPU has the CMPXCHG16b instruction needed to complete the Windows 10 64-bit installation. To update your computer’s BIOS, complete the following steps:

1. Determine first the current BIOS you have on your computer. Open System Information Windows app and type msinfo32 in the search bar. The BIOS version will appear under the processor speed. Record it somewhere.

2. Go to the support page of your motherboard’s manufacturer. Find if there’s any update on the BIOS that you’re currently using. If you find one, download the BIOS update file available. Make sure that you’re looking into the right model and you download all the necessary documentation. Otherwise, the BIOS update might not work.

3. Update your BIOS. Most BIOS update steps are straightforward. Just make sure to follow the steps provided.

Method 2 – Install Windows 10 32-bit version

If updating the BIOS doesn’t work, what you can do is install a 32-bit version of Windows 10 instead of the 64-bit version. Here’s how to do this:

1. Download and install the 32-bit version of Windows you currently have. If you have a Windows 7 64-bit version, get the 32-bit version of Windows 7. The same goes for Windows 8.1. When you do this, you might want to back up your files first. Remember that installing the 32-bit version works like other installations, and could delete some of your files.

2. After installing the 32-bit version, go to Updates and install all the necessary updates. This includes upgrading to Windows 10 if you’re asked to.

3. When you installed the Windows 10 upgrade, you’ll now have the Windows 10, 32-bit version installed. This will be the version activated on Microsoft servers. Despite this, the activated version stored is only applicable to your computer’s hardware, not the version of Windows 10.

4. Download Windows 10, 64-bit version.

5. Prepare an empty DVD or USB flash drive. Use Creation Media software then click the Create Installation Media for Another PC option.

6. Install the 64-bit Windows 10 version you downloaded from Step 4. Make sure not to put anything when you’re asked to input the serial number.

7. Once the installation is complete, you’ll have the 64-bit version of Windows 10.

Method 3 – Buy a new processor/motherboard

If the above two methods don’t work, there’s a great chance that this error occurs because of an outdated processor/motherboard. Your next possible solution is to buy an updated model that’s fully compatible with 64-bit Windows 10.

Method 4 – Download an automated tool

If all else fails, you might want to consider using this powerful automated tool to quickly fix the problem and any other computer-related issues.

If you have encountered the “YOU ARE NOT AUTHORIZED TO ACCESS THIS WEB PAGE AS PER THE DOT COMPLIANCE” error while trying to visit a website using either Firefox or Chrome browser, then read on as this post will guide you on how you can fix this error. Apart from this error message, you might also see an alternative message that says, “Web Page Blocked! The page you have requested has been blocked because the URL is banned as per the Government Rules”. When you get any of the aforementioned error messages when visiting a website, this means that it has been marked. It is mostly recommended to not access the site as it might be blocked for some illegal reason. However, if you are certain that the website is legitimate and safe and you believe that it has been blocked by accident, then you can check out the given methods in this post to unblock and access the blocked or restricted website. There isn’t actually a straightforward way to remove the restriction on the website or the DOT compliance. And it won’t matter what browser you use as you will still get the same error. Thus, the best way to go about this issue is for you to bypass the ISP restriction. But before you proceed, keep in mind that the ISPs (Internet Service Providers) can block any website when a request goes through their servers.

Option 1 – Try changing the DNS

If the request to access the website does not go through the ISP’s DNS server, you might have a chance in accessing it by changing your DNS settings. You can try using the Google Public DNS.

• Tap the Win + R keys to open the Run dialog box.
• Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
• After that, go to the Connections tab and select the LAN settings.
• From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
• Now click the OK and the Apply buttons.
• Restart your PC.

Note: If you are using a third-party proxy service, you have to disable it.

Option 2 – Try to install a Proxy Extension

You could also try installing a Proxy extension or Proxy software as it could also help you access the website you are trying to open as it allows you to access the blocked websites by routing the request through their server. Aside from that, it can also hide it from ISPs to make them look like the content is coming from the proxy servers.

Option 3 – Try using a VPN connection

There are instances when the network that your computer is logged on might have blocked your access to the website you are trying to open and so to fix it, you can try to use a VPN connection. There is a lot of free VPN software out there but just make sure that you install a trusted one. Once you’ve connected using VPN, try to open the website again and see if you can now access it.

Option 4 – Check the Windows Host file

You can also try to cross check the Windows Hosts file to find out if the website you are trying to open has been blocked because if it is, then it’s no wonder why you’re getting the ERR CONNECTION TIMED OUT error in Chrome. There are instances when some third party application modifies the file and add some websites to the block lists. So if the website is indeed blocked, you need to remove it from the list.

Option 5 – Try to contact your ISP

If none of the options given above worked, then you can try to contact your ISP as there are times when DOT clears a website, the ISPs are still blocking it. Thus, it’s probably better if you reach out to them and ask them to unblock the website from their end.

A lot of users connect to the internet are using VPN on their Windows 10 computers which means that their regions could be different from the actual region of their Windows 10 computers. Thus, if you are facing some issues in updating your computer in this kind of environment, specifically the Windows Update error 0x800F0922, you need to follow the tips given in this guide to help you resolve the issue. When you encounter this kind of Windows Update error, you might see either of the following error messages on your screen:

“Windows could not search for updates, Code 0x800F0922 Windows Update encountered an unknown error” Or: “Windows failed to install the update with error 0x800F0922”

This issue might be caused by two possible reasons such as:

1. VPN issues
2. Not enough space on the System Reserved partition

To resolve the problem, here are some tips that might help:

Option 1 – Try disabling the VPN

As mentioned, if you are using VPN, this could be the reason why you’re getting the Windows Update error 0x800F0922 so the most obvious thing to do is for you to turn off the VPN and try to run the Windows Update once more. And if you use a VPN software that works using their software, you can just completely exit or log-off from its account. On the other hand, if you are using a built-in Windows 10 VPN, you can simply turn it off or delete all the settings you have created there. Although it’s understandable that you might have to use a VPN connection to connect to the work network, you really have to disable it at least until the Windows Update is no longer stuck in the error 0x800F0922. It would be best if you do this when you are not working.

Option 2 – Try to free up space in the System Reserved partition

The System Reserved partition is a part of the hard disk created when Windows is first installed on it. It is where the Boot Configuration Database, Boot Manager Code, Windows Recovery Environment, and the reserves space for the startup files are stored. And as mentioned early on, the error might be due to some insufficient space in the System Reserved partition so the next thing you can do is to increase the space in this partition. Note that it is a complex process so you need to make sure that you have made backups to all your data on the computer. So if ever something goes out of hand, at least you have copies of your important files in case you aren’t able to boot into the system at all.
