Visual Studio 2015 RC Community will not install, says it is already installed

Question

As the title implies, I am not able to install Visual Studio 2015 RC Community, and I keep getting the following errors. For the record, I am on Windows 8.1 Professional.

Answer 1

I banged my head over uninstalling 2015 RC for hours. I found quite a few discussions about uninstalling RC but nothing worked.

I used variations of vs_*.exe /uninstall /force but nothing worked.

I do not remember, but I think I must have performed an "online" install of RC and found a file with the same filedate as the install date.

The following worked for me: vns_full.exe /uninstall /force

Thanks to all the people in all the forums that eventually helped me find a solution to this uninstall RC problem.
