| | Re: Remote Assistance Vista 64-bit - probable firewall/router issu the answer is yes, and I just solved the problem. It was that the invitations were being sent as Vista only, and by luck of the draw the remote machines were Windows 7 Beta and Windows 2008 respectively. When it worked inside, it was from a Vista machine. Now it works from the outside. Thanks. "Robert L.
