When I implemented AnyConnect for the VPN access, many of the users report errors when they downloading or disconnecting anyconnect client. I attached some screenshot. Other errors like " Cisco AnyConnect VPN client downloader has encounted a problems need to close" " Active x control not be launched"
Looks like AnyConnect is not stable, is any special requirement for AnyConnect like Local-PC security setting, antivirus, java, etc ???
