For other reasons, I had to reinstall my Windows from scratch so, I took the chance to test a really "clean" GSX install, which is not always easy to do. And I can confirm there are no problems whatsoever with the current version, which worked at the first try, without having to configure anything, not even the antivirus ( default Windows Defender ).
So, if you still have problems, contact me in private to arrange a remote assistance session.
