Office Status: 108 Invalid VLK
Microsoft Office Professional Plus 2007 - 108 Invalid VLK
Unfortunately, the installed copy of Microsoft Office Professional Plus 2007 is non-genuine because it is counterfeit. The invalid product key was never issued by Microsoft and was likely created by a counterfeiter using an illegal product key generator (KeyGen). You can review your options by visiting Microsoft Genuine Advantage and clicking on Validate Office. When validation fails, you will be presented with a Get Genuine button to click on.
