Visual Studio Pointing to Dead Drive

Hello,

My HDD died on me, as I have an SSD as my boot drive I decided to not do a clean OS install (bad idea, I know but I’m not quite ready to do that). As a result of the HDD switch I have bad references to the drive that does not exist anymore, including the compiler location for VS. Is there a way to fix this without having to perform a clean OS reinstall? I know I will probably have to fiddle with the registry but I have no idea where the offending key is.

Thanks.
