Sometimes one of these works for a similar problem 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.

My system will not open any excel file attached to outlook. The system will
open a new excel page (Blank) instead. The same trouble happens if the file
is loacted on my desktop. Files on the desktop can be opened if selected from
the "File Open" icon....?
