Sometimes one of these works when you're having trouble with double clicking on
the file in windows explorer:

Tools|Options|General|Ignore other applications (uncheck it)

--- or ---

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.

Maybe one of these will work for you.
