VS 2017 setup the product definitions failed to load

I tried to upgrade my Visual Studio 2017 RC to the release version and got an error product definitions failed to load

The way I got the installer to work was to delete the folder %LocalAppData%\Microsoft\VisualStudio\Packages\

After that running the installer I was able to update my install to the released version
