Greetings Dave,
I tried both and it still didn't work. I just installed Office 2007 and ran
across this problem of not being able to get an excel file opened from
Windows Explorer. I tried the Tools Option below, but the Ignore box was
already unchecked. Then I tried re-registering excel (which seemed to run
okay), but it didn't resolve the problem. I also notice that when nothing
comes up if I go into the body of excel (where the spreadsheet should be) and
right click, an "open" option comes up. This sends windows to a directory
structure (files in my default folder)". Then if I hit CANCEL, the original
file I tried to open comes up. Do you have any other ideas? I also just
installed XP Service pack 3 - could that be messing me up?

Thanks - Steve

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.

I'm running Office 2000 and recently have found that double-clicking on an
existing Excel file won't open the file, it only opens the Personal
Worksheet, but I can open the file using File Open. I thought this might be
related to the fact I'm getting low on resources errors when I run Word, even
thought I have 512Mb of RAM and no other applications open.
