Hi Malcolm and welcome! I've also (rather painfully) gone the Win 7 64-bit route, and now having got things sorted am reaping the benefits - it is much faster than Vista. Do you get to the stage where you're prompted to enter "Station Information" and can't get out of the cycle? As with Vista, I've installed 3.13 to "C:\AirNav System\AirNav RadarBox\".... folder, plugged in RB, would it find the drivers and would it work - No. Removed RB, shut machince down, re-started (no RB), loaded V2.01 from CD - all OK - enter PGANRB1 + Serial No., get to screen prompt for Stn Info, enter info, connect RB and Voila - still no connection/drivers. Shut machine down again, re-start and plug in RB - go to control panel, device manager, and there's RB with yellow triangle under other devices, told pc I wanted to update drivers and then on next option told pc to go to C:\AirNav Systems|AirNav RadarBox\Drivers and voila, it loaded drivers. Start RB software and all OK. Shut down again. Re-start, go to Control Pane - Programs, uninstall RB2009 v2.01, shut down, re-start with RB connected, clicked on RB2010 v3.13 ands everything working as it should do, a long work around (took 40 minutes probably) buyt it worked for me as a total techno-numpty - I hope it helps! Give it a try and let us know. I'm running Norton 360 v3.0 - no problems.
