Rob,
I just tried installing on a Win 10 machine and it installed fine. The only thing I saw was that the anti-virus program thought it was suspicious (due to it being an uncommon download), so I had to explicitly tell the AV prog to accept it. Is it possible your AV is disabling some part of it? Perhaps try re-installing and make sure the AV does not do anything, or temporarily disable the AV while installing it?
