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:
The first thing you can do to fix the error is to try running the System File Checker or SFC scan. System File Checker is a command utility built into your computer that helps restore corrupted files and missing files. Refer to the following steps to run it:
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:
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.

Once this error code is encountered, it's a clear indication that your Operating System has malfunctioned. This could be a consequence of an incorrect or failed installation of software. The software might leave invalid entries in the Windows registry. Improper shut down of your system and a malware attack are also causes of error code 0x8007007e. Additionally, someone with little or no technical knowledge might have deleted a system file by accident. Missing system files can also equate to other error codes such as registry error code 19.
You may not always be able to prevent issues from affecting your computer, but proper measures can be taken to limit your risk of experiencing problems like error code 0x8007007e. See the following suggestions below:
System File Checker is a Windows tool that allows users to check their system for corrupt or bad system files. The utility scans for corrupt files and repairs them as well as files that may have gone missing.
Depending on the type of Windows operating system on your computer, you may need to follow varying instructions. However, note that Windows operating systems including Windows 10 and Windows 8 or 8.1 and Windows Vista all provide access to System File Checker via Command Prompt.
Once you run System File Checker, the tool should be able to repair and replace corrupted files. However, in cases where the repair process does not take place, you can attempt a manual repair by replacing the corrupt file the tool identifies with a good file. The process may require technical knowledge of Command Prompt so consider help from a Windows repair technician or consider contacting Windows for instructions based on your computer’s operating system.
The System Recovery Options menu in Windows contains many tools which can enable users to resolve serious errors. In the case of Error Code 0x8007007e, one of the best tools in this menu is System Restore.
When an error occurs which inhibits users from accessing key functions on their system, System Restore enables the user to restores the computer to an earlier period without causing harm to files, photos, or documents.
However, once you run this tool, you will only be able to access files available within the period to which your computer is restored. For this reason, carefully consider which period is best suited to your purposes. Also, ensure you restore the system to a time when error code 0x8007007e was not present on your machine.
If System Restore does not resolve the error, you may undo the restoration changes. Ensure you have sufficient free space on your machine hard disk before you proceed (300 MB at least for hard drives above 500MB or at least 50 MB for smaller sized disks).
When it comes to resolving error codes, it can often be a frustrating and tricky venture, especially when you are attempting to fix the problem manually. The Internet is awash with bits and pieces of instruction, some misleading at best with uncertain success rates.
But what if there was a one-stop-shop or better yet a tool that offered solutions for error codes including 0x8007007e? Download a powerful automated tool that offers easy and effective, user-friendly solutions for users with varying error code problems.
