Installing SR13 fails on Win 7 Enterprise

I am trying to install rh50_en-us_5.13.60523.20140.exe, but I get the following error from the installer:

Unsupported Window Version Detected

Rhinoceros 5 requires Windows XP SP3, Windows Vista or Windows 7.

Please upgrade your computer to a compatible version of Windows before installing.

FWIW, previous versions installed fine.

Please find the reason and solution here:

That was exactly the problem, thanks for the help, Kelvin.

I had to follow the debug steps on your help pages to get past a 1603 error, and uninstall all old files, but eventually got it to work. I very much appreciate how much work has gone into the installation debug pages on your website!
