I have a client with a small business network on a domain of around 10 computers, and Microsoft Office Professional Plus 2010 has been installed on them for a couple months and working fine.
Just recently, I needed to change the software key [we received a different key for an updated volume license agreement, exact same product], so I logged in to each machine as an Administrator and used the handy option to "Change Product Key" within the help menu of any Microsoft Office application. Afterwords, I could launch Microsoft Office applications with no problem.
As users logged in to their computers, they reported seeing the message "Microsoft Office Professional plus 2010 cannot verify the license for this product. You should repair the office program by using Control Panel". I logged in to one of the computers as a user who hadn't logged in to that computer before [who didn't have a local profile stored yet] and that user was able to open Microsoft Office with absolutely no issues. It seems that it's just effecting users that already had a profile on the computer at the time of the product key update. Is there a registry tweak or a file within the profile that needs to be deleted/modified that would fix this? Do I actually just need to go to the control panel and run a repair, even though the Office apps work just fine under any new user and the local administrator?
Any help would be greatly appreciated. Thanks in advance!
