If, like me, you own a legitimate copy of Office 2007 but for some reason are getting the “This copy of Microsoft Office is not genuine” notification message after installing the latest OGA update, you will want to use this workaround to disable the annoying pop up messages.
Using ‘My Computer’, navigate to C:/Program Files/Microsoft Office/Office12 and right click on the Office application you have installed, e.g., winword.exe.
Right-click an select the ‘Run as Administrator’ option to run the application.
Once Word has opened, click on the Microsoft button (top left) and scroll to the very bottom where you will see a button called ‘Options’. Click this and then select ‘Add-ins’.
Select ‘Manage: COM Add-ins’.
Uncheck the option for ‘Office Genuine Advantage Notifications’.
Now repeat this for every Office Application you have installed.
This will only prevent the “This copy of Microsoft Office is not genuine” notification message from displaying. The software will still be installed.
