While using sp1 Excel 2000, or Excel 97 the *.XLS file opens without
any trouble. However, after installing Office 2000 sp3 - Exce
2000
can't open the *.XLS file and gives the message "Unable to open th
file".
Excel 97 still uses the *.XLS files just fine.
How do you either remove Office 2000 SP3, or get around this proble
?
Thanks.

Found a work around
I am using another anti-virus product so. . .
After Office 2000 SP3 Install you may see the
error -> "Unable to open file" When you try
to open an existing Excel *.XLS file.
Open a DOS window and change directory to the
root directory using the -> "CD \" command.
Find file -> officeav.dll using
the -> "Dir officeav.*/s/p" command.
In my case the file is in directory
"C:\_Norton2\IE2005\Norton AntiVirus\"
While in DOS, change to that directory.
CD "C:\_Norton2\IE2005\Norton AntiVirus\"
Use the Regsvr32 command to unregister the DLL.
Regsvr32 /u officeav.dll
Then rename officeav.DLL to officeav.old
Do a reboot of the computer.
