Windows 7 Windows Media Center does not start - no mscoree.dll

[matkus]

Hello.

Few days ago when i started Windows Media Center to watch TV from TV tuner windows displayed error message, that mscoree.dll is incorrect and needs to be fixed, so i've started chkdsk as it suggested and since then i can't run WMC. It says, that it can't find mscoree.dll file.

File itself exists and is located in windows/system32 directory and have ~400kb. i've tried to copy that file from my 2nd computer, but that didn't help.

SFC /scanall didn't help. It fixed some files (after granting permission) but not this one (it said it fixed it, but error still appears).

If i copy mscoree.dll into windows/ehome directory, when starting Media Center i don't see any error message, but nothing happens, process is terminated immediately without any error message.

Is there any other way to check for missing/invalid files? In old times (somewhere around last ice age ), for example on windows XP, you could start installer from CD and tell it to fix instalation, but i don't see anything similar on Win 7.
Windows Restore sees only points from today and yesterday and nothing older, so it will not help.

All other programs so far works OK for me except WMC.

It seems like you are encountering issues with the mscoree.dll file affecting the functionality of Windows Media Center (WMC) on your Windows 7 system. Here are a few steps you can take to address this problem:

Steps to Resolve the Issue:​

1. Register the mscoree.dll File:
   • You can try registering the mscoree.dll file using the Command Prompt. Here's how you can do it:
   • Press Windows Key + R, type cmd, and press Enter to open the Command Prompt.
   • In the Command Prompt, type the following command and press Enter:

     bash regsvr32 %windir%\system32\mscoree.dll

   • After registering the file, restart your system and check if WMC works correctly.
   []Repair the .NET Framework:
   • Since mscoree.dll is related to the .NET Framework, repairing or reinstalling the .NET Framework might help resolve the issue. You can download the appropriate version of the .NET Framework from the Microsoft website and install it on your system.
   []System File Checker (SFC) in Safe Mode:
   • Try running the System File Checker (SFC) scan in Safe Mode. This can sometimes help in repairing system files that were not repaired during a regular scan.
   • Boot your computer into Safe Mode and run the SFC scan again.
   []Check Event Viewer for Errors:
   • You can check the Event Viewer for any specific error messages related to Windows Media Center or the mscoree.dll file. This might provide more detailed information on what is causing the issue.
   []Reinstall Windows Media Center:
   • If the issue persists, you can try to reinstall Windows Media Center. This can be done by going to Control Panel > Programs and Features > Turn Windows features on or off, and then unchecking and rechecking Windows Media Center. Follow the on-screen instructions to reinstall it.
2. Consider Windows Updates:
   • Ensure that your system is up to date with all Windows updates. Sometimes, installing the latest updates can resolve issues related to missing or corrupt system files.
