How to Change an Office 2010 License/Product Key

Issue: You go to activate Microsoft Office 2010 and you receive a message stating, “Your copy of Microsoft Office Professional Plus 2010 cannot be activated because the specified Product Key has already been activated the maximum number of times permitted for your software license as specified in the Microsoft Software License Terms.”


The solution is to change the product key to another product key. I will show you three different methods of changing the License Key






Navigate the registry to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\14.0\Registration\ and delete the whole “Registration” key located under the “14.0″ key
Right click “Registration”
Select “Delete”


Press “Yes”

Close Regedit, Restart an Office 2010 application. You should be prompted to reenter your License Key
