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.

When I try to open Excel workbooks, worksheets, spreadsheets, or any of my
Office Documents associated with Excel from shortcut, my pc, search, browser,
exlorer, etc, Excelwill start but does not open file. All I get is a blank
window (not a wkspc) within the Excel program. To open the file, I must
browse with Excel to same location I tried to open from originally. This
happens with local file or a network shared file and just started happening,
as I never had this problem in the past 3 yrs.
No new programs have been installed that I can recall, no others have been
on either PC. Have tried all I know to do and now seek assistance.
