I use MS Office 2003 on Windows 7 (I hate Office 2007) on a computer I bought a couple of years ago. The computer came with a trial version of MS Office Home and Student Version 2007, which I never used (didn't actually know it was there as it doesn't show up on start all programs). The other day I opened an attachment that contained MS Word 2007 docs (didn't know they were this version) and now every time I go to open an existing Office document (any), the trial version pops up trying to install. I can get to my document after closing a bunch of boxes and it will be in 2003. However, today after closing the boxes the document came up in "compatibility mode" which was 2007. I hate 2007 and want only 2003. Help!
