Excel workbooks opens in Outlook. Why?

[Guest]

I recently installed ACT! CRM onto my PC. Now when I open Excel and select a
document it opens in Outlook. I have spent hours trying to figure this out.
Please HELP. Thanks

I don't use ACT! or Outlook.

But the first thing I'd try is this:

Close Excel and
Windows Start Button|Run
excel /unregserver
then
Windows Start Button|Run
excel /regserver

The /unregserver & /regserver stuff resets the windows registry to excel's
factory defaults.
