PRF file quit working

We had built a custom PRF file for Office 2003 SP3 that ran the first time a
user opened OutLook to automatically create his OutLook Profile (we use
Exchange).

This worked fine, and, we had it on a clone that we use Ghost to create
multiple copies from, and, again, all this worked fine.

We had not installed OneNote and FrontPage, so, ran those installs to add
them into the rest of the suite on our Master Clone, and...now the PRF
doesn't run when OutLook is first run.

The file is still there, and, if double-clicked, will run and create the
profile, so...looks like we broke some kind of link (Registry, INI/INF
file?)...anyway...not sure what's broke.

Can somebody point me in the right direction?

Thanks!
