Visual Studio 2010 Corrupt after uninstall of Office 2010

Hi

I have an Excel add-in project in Visual Studio 2010. When I try to debug it I get the following error. I just uninstalled my Office 2013 Trial a minute ago and am sure that this
has caused the issue. How do I resolve this. I can't run a repair on my Visual Studio 2010 software as  the disc that I have is damaged
