For a Microsoft Office XP version of this article, see 300273.
When you try to activate a Microsoft Office 2007 suite or Microsoft Office 2003, you may receive an error message that is similar to the following:
Your installation cannot be activated because you have activated up to the limit for your Product Key. For details about the maximum allowed number of product activations, close this wizard and review the End User License Agreement, available through the Help menu of this application.
If you believe that you are getting this message in error, click Back and choose the telephone option. The telephone activation system will provide you the opportunity to speak with a support representative about all activation issues.
This behavior may occur if you installed an Original Equipment Manufacturer's (OEM) copy of Office, and you already installed and activated the same OEM copy on another computer. OEM copies of Office 2007 or Office 2003 can only be activated on a single computer.
Note You can remove and then reinstall Office by using the same product key on one computer successfully.
