After installing the latest Windows updates, I was unable to open any Word or Excel programs on my computer. The doc opened, but immediately an error message dialogue box came up: Error message: Microsoft Office cannot verify the license for this product. You should repair the Office program by using Control Panel. The only 2 options available were to click the X to close, or click OK button. Both resulted in the doc closing. Control panel --> Office did not display an option to repair. I run Windows 7 Home Premium 64 bit and Office 2010 Home and Student ... both legitimate store bought products with product keys. I even tried to uninstall and re-install Office with no change in the results. I uninstalled the Windows updates with no change, then re-installed them. System restore did nothing to change the issue. I would appreciate any help with this issue. Thank you.
