I installed tightvnc viewer on the windows 7 64 machine and enable screen sharing on the imac.
When I try to connect to the server via the interface as in the attached screenshot called servername.jpg (where the word servername is replaced by an ip adres of course), I get the error message as in the attached screenshot named error.jpg
Which port should I connect to ?
What is the format to be used ? servername:port ?
