DLL files have certain functions that help the programs in the computer run properly. One of these DLL files is the Msvcr120.dll_clr0400.dll. This particular DLL file is responsible for the extraction of the required resources during the installation of a program and is used when the program is launched or when games are launched in the C++ language. However, a number of users recently reported that they’ve encountered an error that says, “Msvcr120.dll_clr0400.dll is missing” when they tried to install an application or when they tried opening an application.
This kind of error could be due to several factors. It is possible that the DLL file is corrupted or there are some programs that interfere with the DLL file. On the other hand, it is also possible that it has been infected by a virus. To resolve this error, here are some potential fixes you need to check out:

You can also troubleshoot the isDone.dll error in a Clean Boot state. It could be that there are some third-party applications in your computer that are preventing the application from getting installed and to isolate this possibility, you need to boot your computer in a Clean Boot State and then try installing the program again. Putting your computer in this state can help you identify which program is the culprit and thus isolates the problem. In a Clean Boot state, your computer will start using only the pre-selected minimal set of drivers and startup programs. Note that you have to disable and enable one process at a time.
You can also try to re-register the DLL to resolve the problem. The Regsvr32 tool is a command-line utility that can be used to register and unregister OLE controls like DLL and ActiveX (OCX) controls in the Windows operating system. Follow the steps below to use it.
Note: Replace “[DLL file]” with the name of the DLL file that was pointed out in the error.
The DLL file might also be infected with malware or virus and to eliminate it which could explain why you’re getting the “Msvcr120.dll_clr0400.dll is missing” error. Thus, you have to scan your computer using security programs like Windows Defender.

When you upgrade your Windows 7 or Windows 8.1 system to Windows 10, you’ll undergo a phase called Out of Box Experience, or simply OOBE. This phase is intended to allow users to customize their Windows 10 experience, which includes defining personal settings, creating user accounts, and more. Some users reported having issues when creating their user account during the Out of Box Experience (OOBE) on Windows 10 upgrade. Some also reported issues about non-responsive behavior (Welcome Back) page.
Error CausesUnfortunately, there’s no known cause for this error. However, some users reported that this occurs when:
Your Windows 10 upgrade will not be successful if you’re not able to create a user account or finish the Out of the Box (OOBE) phase of the installation. Here are some methods that will help you fix this manually.
Some users reported that waiting for about an hour and retrying the process again will solve this problem. It’s also recommended that you keep your computer in a ventilated place while you wait to retry the process.
This method has 2 requirements in order to work.
If you meet these two requirements, you can solve the error by following the steps below:
This method only applies if you’re a laptop user.
Instead of connecting to a Microsoft Account after the set-up, you might want to try creating a local account. To do this, follow the steps below:
If the steps above don’t work, you might want to try Startup repair.
In order to do this step, you need to have official Windows 10 ISO files.
After doing the steps above, there’s a chance you get an error message that says “installation cannot be completed in safe mode”. When you see this, just press Shift+F10. This will execute and open the command prompt of your computer.
From the command prompt, you can try and create a new user account.
For example, net user Username Password /add
The username here should be replaced with the account name you want to add, and the Password here should be replaced with the password you want to use for the account.
After replacing the username and password on the text, press the Enter button on your keyboard. You’ll know if the command is successful once you see the message, “The command completed successfully.”
You can now close the command prompt. Restart your computer and try to log in using the account you just created.
If all the above methods still don’t work, it might be best to try automated software to help you fix this problem.
