Make sure that during Ace Stream install there no any false-positive alerts from Windows Defender or other AV software and there no any Ace Stream files in the AV quarantine.
Also you may check for “MaxUserPort” parameter, refer to this article for details -

Thanks for your help, Windows defender is the issue. I have excluded the ace stream in the defender and installed it.
