Only thing to try is a repair install, also sfc /scannow says that it found problems, but cant be fixed, see the log, but i cannot make sense of the log, too much info.
Another thing, i put the .Net Environment and .Net Framework 3.5.1 back to enabled in Windows Features. As expected MSN and Trillian crash on open again.
But when they were disabled mw Moder Warfare 2 woudnt run, hence my reason to re-enable them, but now it crashes on open too, even though my PC is back to how it was originally.
Arghh driving me nuts, im at Uni so i dont even have my Windows Disk with me
Also another program thats not working, SMplayer, crash upon opening a file.
Im sure its all related as its all happened at the same time. Isnt there a way to completely remove .net Framework and reinstall it?
