Open the Control Panel, then 'Add/Remove Programs", then click on Office 2010 Pro, then select "Change". Office setup will load, then select "Repair".
It would also help to visit the computer manufacturer's website and install any updated drivers for you computer model. Such updated drivers will frequently fix the issue with various programs such as Office.
If this doesn't get it done, you'll need to uninstall, then reinstall Office. You're not alone with this issue as we've seen quite a few folks have similar issues with Office and other programs when upgrading to Windows 10.
Hope this helps.
Does anyone have a solution besides having to reinstall and re-register my Office 2010 Pro software. No I do not see any need to keep buying upgrades.....My disks and software are legitimate.
