In case anyone is having issues getting Windows 7 to accept inbound connections for Real VNC, use the workaround at this link that was discovered with Vista. Worked like a charm for me.
if you download and install version 4.5.1 it's the version for win 7 for home premium, starter and those. I haven't been able to get it to work on 7 pro or above, probably because the built in RDC in win 7 pro and above. Computer, system properties, remote settings, allow remote control of this computer. I'll see if there is a fix or workaround for real vnc for win 7 pro.
