Fetch the Blender install from MSI registry 

Somewhere around Blender 2.75, the SCONS build system was removed and
CMake reigned supreme. The installer was of course changed to a Windows
Installer generated by CPack. Unfortunately for us, the registry keys
changed. Windows Installer's registry stuff sucks, but this is the
easiest way for us to get at it.
