Reconnect after installing software that requires a reboot.
Most of these folks have, in the past, installed TeamViewer at my request. Most can't do much else. When they need help, I tell them, by phone, to run TeamViewer and tell me the password (PIN). If they needed a Reboot I'd use the "Reboot" TeamViewer command and wait for their system to comeback up. TeamViewer then gave me the [Reconnect] option to continue.
Can you give me instructions for the "friend" to do after installing RA, so that I get complete control, including after Restart, after giving me the initial PIN?
