.NET Runtime 2.0 Error after BSOD and ChkDsk

It all started with a BSOD while playing GTA IV, followed by a ChkDsk that deleted quite a few files which I thought was a good thing until windows loaded. Already I noticed things like login details for windows live messenger being wiped along with the 'remember me' settings. But that wasn't a big deal. What got me is that I could no longer play the game through my saves or online because GTA IV uses Games For Windows Live (GFWL) and that uses .NET Framework which seems to have got corrupted, or at least something corrupted is conflicting with it.

Tried opening the GFWL client through windows but all I see is a blue intro splash before an error crash. Re-installing with the latest version did nothing, tried repairing/modifying GTA IV too.

Ultimately I even tried to System Restore back a day but it wouldn't let me as apparantly "no changes" have been made, which is BS.

In Event Log under Applications there is an error that happens at the same time the GFWL client fails to open, it says .NET Runtime 2.0 Error. I have .NET Framework's 2.0/3.0/3.5 SP1 installed and did a repair on the 3.5, as well as a full re-install and complete clean with the .NET clean up utility which didn't help with the issue at hand. So I'm pretty stumped at what to do now, as well as annoyed.

Later on I tried several other restore points neither of which worked so this leads me to believe that my System Restore is also corrupted.

I should also include that by creating a new windows user account the applications work just fine. This is on Windows XP SP2.

With further troubleshooting to confirm the problem I ran http://wikipediaexplorer.blob.core.windows.net/wpf/WikipediaExplorer/publish.htm
This didn't work on the main account but worked and installed properly on the test user account.





I get the following error when attempting to install on the main account
Cannot Start Application; Application cannot be started - and after clicking on details:

I have been trying to resolve this for days without much luck so any help is appreciated.
