Herb,

I ran into the same problem. SP2 Auto-installed (or tried to - it reported
that file 2 of two installed, but 1 of 2 failed. I did not notice anything
particular with the computer's operation until today. I was going to work
with Excel and got exactly the type of problem TomC describes. I can't load
from the disk, the CAB referenced is not on the disk or the HD, I have now
Excel icon in the Start --> programs area of Office and when I try to launch
a file I get the Windows installer.

I am pretty frustrated, because I tried to restore to an earlier point and
the restore was unable to complete. Any help would be appreciated.

Thanks for the help.
