It would appear the the installation didn't remove all of the previous software. This can happen if it's a different suite or from a different source especially.
Uninstall in the normal manner via Control Panel > Programs > Uninstall a Program (Add or Remove Programs if XP) (Don't miss this step as it decrements the number of licenses in use on the online account)
Run the MCPR cleanup tool listed under Useful Links at the top of this page and reboot.
Reinstall the latest software from your online account.
Hopefully that will fix this annoyance.
