Hi. Can somebody help me! When I shut down I get 'This program has performed an illegal operation'. The last time I shut down I didn't get the dialogue box but vertical lines on my screen. I run norton to try and fix problems and their was one problem it couldn't fix: C:\program files\common files\installshield\professional\run time\10\00\DotNetinstaller.exe...cannot acces a necessary file, "mscoree.dll," ...This is the message it gave me. Does this problem have any connection with shutting down? Please help. Anybody. Thank you!!!!
