Fix Office 2010 Activation Error

Problem:

When I try to activate Office 2010 Professional Plus x64 on Windows 7 x64 RTM, The activation fails. I was able to retrieve some entries from the event log which may point to the problem (pasted below). I downloaded the beta twice, and used two different keys in the hope that the initial key was corrupt. This was not the problem. Office seems to be working correctly, but the title bar is red, and has a comment "(Product Activation Failed)". I have tried activating using Word and Excel, and both exhibits the same problem, the activation code is accepted, but the product does not activate.


Solution :

Can you try activating (setting the key) through control panel / uninstall a program / right-click Office 2010 / choose "Change" (not uninstall).From the setup dialog that comes up (may take a minute) you are supposed to be able to enter a key (I cannot myself; possibly because mine was installed with an MSP and is set to use an Office KMS). But I have been told that you can do this.
