Why can't I connect to a contact that I want to help?
Windows 8
If you still can’t connect once you’ve been invited, try using the
troubleshooter by tapping or clicking Troubleshoot
in the Windows Remote Assistance dialog box. The
troubleshooter is only available on PCs running Windows 7, Windows
8, and Windows RT.
If you're still having problems after running the Windows Remote
Assistance troubleshooter, ask the person you're trying to help to
create a new connection using Easy Connect.
