I recently installed Excel 2003 on a computer that has 2002. I wish
to run both versions; for testing purposes. However, any xls will be
opened with 2003. Now normally you can ReAssociate the files to the
correct version (like I had done with Access 2002 & 2003). With
Access I'd have 2 file types to choose from, but with Excel it only
has one which is linked to 2003.

I decided to throw out my intelligence and play with File Type
extensions. So after about 30 minutes and totally breaking the links
with excel, I system restored the computer (and my sanity) back to
original state before installation. All is good now, but I would
still like to:

Have both versions of excel
Be able to choose the versions so if a user double clicks an existing
excel file it opens 2002 (not 2003)

Suggestions?

thanks in advance!
