Still having issues here. In the UK, local time 19:55. MSP Connect will not 'connect'....

I think I have solved my own problem!
I found that if you run both the Supporter (Full version s/w) AND the Client (QuickSupport s/w) AS ADMIN, then it is possible to access and control management functions such as the Task Manager and the Firewall.
I have changed desktop icons for the Full, and the Client software to 'run as Administrator'. It then works. Thought it best to post this solution as it might help others.
