FIX : give the other user ADMIN privileges OR go back to admin account to update (make sure the program is installed on the C drive ... that is where the updates will look for it.)
Sorry, did not reply for this: The other user is also an ADMIN account. So, that was already done. And, the program is installed on the common C drive, which I assume is why it works from the "other" user account. Just cannot install from the other user account. But, hopefully, I do not have to install again! Everything else appears to be working OK now. Time will tell!
