If you are using Microsoft’s next generation Office Suit (though still in beta test, and assumed to be release this quarter of 2010), you might need to activate it. Here, is a simple guide to activate MS Office 2010. Screenshots are from MS Office Pro Plus 2010 in Windows 7 Professional edition. This same should apply to Vista and XP too.
In order to activate Office 2010, open any Office application (eg Word as we took here), alternatively you can type Activate Office in search box of start and then goto Info menu under File, you shall see Product Activation Required saying ‘Microsoft Office Professional Plus 2010 requires a valid product license. Activate your product key now to obtain a valid product license.’ Click this message to proceed.
If your copy of Microsoft Office is not activated, you need to activate it. Since this software is designed to corporate or institutional customers by Microsoft, you need to connect your computer to your corporate network to complete activation. Your system administrator might help you.
While changing the code, we got the Setup Error screen which says “The setup controller has encountered a problem during install. Please, review the log files for further information on the error.”
