I have looked everywhere on the world wide web for an answer to my problem but found none.
A week ago I tried to install a program which used windows installer (msiexec.exe). It came as far as: decompression files and then it stopped. Then my computer started to mess up. I couldnt't ctrl+alt+delete or open task manager, open the start menu or do any other action that requires explorer.exe. If I pressed the start menu, it came up 5 minutes later. In addition my mouse started to freeze in intervals. Only way to get rid of it was to force a restart.
I figured that there were something wrong in my windows files and did a clean reinstall of windows 7 64bit home edition. Then I could install a few programs (was doing so while installing from windows update). I got the programs i wanted installed and thought it was fixed. Then yesterday I were going to install another program (ventrilo and acrobat reader, both use windows installer) and the problems started again.
The only logical explanation I can find to this problem is that something from windows update messed up my windows installer. I have tried everything I can think of to fix this problem except for doing a new clean reinstall of windows 7, and then not using windows update afterwards. Except for this my computer works perfectly fine.
Please help a frustrated norwegian
