Microsoft .NET Framework Problems

Question

So just after Christmas, my computer started coming up with these error messages when I tried to use certain programs. It started with GoPro Studio. So I went to the GoPro forums and they held a remote session with me. But they said that it was a problem with the Microsoft .NET Framework.

There were several files that it says are either not designed to run on Windows, or contain errors. The most common one is "MSCOREE.DLL".

"C:\WINDOWS\SYSTEM32\MSCOREE.DLL is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support. Error status 0xc000012f."

This is the message that pops up for GoPro Studio, but it can come up for other programs too. Like Windows Media player, and CyberLink PowerDVD 12. I've tried to install the programs again and reinstall .NET Framework. Nothing was fixed. This is Windows 8.1 and I don't want to upgrade to Windows 10. If anyone knows anything, please help.

In case this is any use, I have some screenshots of the error messages as well.

Answer 1

I actually did that in the remote session. I'm not sure what to make of what it found, but I did take some screenshots of it.

"Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.log windir\Logs\CBS\CBS.log. For example C:\Windows\Logs\CBS\CBS.log. Not that logging is currently not supported in offline servicing scenarios."

The problem didn't go away even after several restarts.

Hi,

Welcome to the Microsoft Community.

I would suggest you to perform SFC scan. SFC /scannow is a super-useful command you can use in any Windows version. When the SFC (System File Checker) command is used with the /scannow switch, the tool will scan all of the important Windows files on your computer and replace them as necessary. Missing and corrupt operating system files (like many DLL files) are arguably the biggest cause of major Windows issues.

Refer to these steps to perform a SFC scan:

a) Press Windows key + X, select Command prompt (Admin) to bring up elevated command prompt.

b) In the command prompt type the following command: sfc /scannow and press enter.

c) After the scan, restart the computer and check if the issue persists.
