I am running Windows 8.1.

I had two versions of Office on my computer-Office 2010 and Office 2013 out of which Office 2013 was not activated but Office 2010 was activated and was working fine.

I got an update for Office 365 and I installed that by mistake.

So I went to Programs and Features and I uninstalled Office 365.

After the uninstall, Office 2010 is also not working.

Please help me.
