proret.msi not found

[Paul]

I recently upgrade my motherboard in my computer.
Needless to say this caused office to require itself to be
re-licensed. Fine. Well, it starts the procedure and
then reports that proret.msi cannot be located. It was
attempting to search the CDrom drive, so I inserted it and
still proret.msi cannot be found.

Can someone provide me with some information so I can get
my installation of office working again?

Thanks,

Paul
