Sometimes one of these works:

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.

when I launch excel thru a file in my documents, I get a new workbook, but
when I open the file from within escel it works. Also when I launch by
clicking an attached outlook excel file it does not launch (file not found
message). Does anyone have any idea what is going on here?
