The newer control center doesnt seem to have this issue, I was out at clients site last week it installed over the free version they were using properly and updated no worries(using the remote install).

Ive installed AVG with the central control module just setup an old workstation to look after this easiest software ive ever installed, also allows you to change keys and do remote installs takes about an hour to install on machine then remotely load up 20-30 computers.
