I sent a setup program to a user that had all the required files for a
program I wrote in VB.

Unfortunately, I sent him the one for Outlook 2000 instead of Outlook
2003.

Anyway, he cannot delete MSOUTL9.OLB from his machine and the program
will not work. When he tried to delete it, the system said he can't
do it.

My program worked fine on his machine before we put the MSOUTL9.OLB on
there.

Can you tell me how to get rid of the MSOUTL9.OLB file while keeping
the MSOUTL10.OLB file?
