Word, Excel, Powerpoint reconfigure on opening

[stealth2920]

I had this issue when I first installed the 2010 beta last year. I can't remember how I fixed it. It has been running fine until a couple weeks ago. Every time I open a word, excel or powerpoint file, the windows installer reconfigures like it's reinstalling or something. Just clicking the word, excel icon doesn't do it. It only happens with saved word, excel, powerpoint files. Any clues?

Did you try to turn the autosave off. E.g. in Word Options > Save

Tried that but didn't change anything. As soon as I click a word, excel document in My Documents folder it does it. Does not do it when clicking the regular icons to open, only documents already saved.
