Greetings to everyone!

I am having a problem of Mapsource locking up (on two other computers) after installing CNNANT 2012.10.

I have a NuMap Lifetime update for my Nuvi. It took the update with no problems. I told it to install on both my computer and my Nuvi. After the installation was complete and working, I replaced Mapsource.exe with patched version 6.15.11 Mapsource.exe. Everything works fine, and was able to unlock, select & install maps on my 60CSx.

Problems started when I tried to replace the old 2011.4 with the new 2012.10 on my laptop and other tower computer. 2011.4 was already working perfectly on both other computers. All computers are running Windows XP Pro edition. I copied all of the files from the 2012.1 installation (gmap folder, etc.) to a DVD.

On both other computers, I ran the .msi file from the DVD, and it said that 2012.10 was installed successfully. I replaced Mapsource.exe with the same patched version 6.15.11. I also copied the gma and unl files to the new computers. When I start Mapsource, it comes up fine, and CNNA 2012.1 is fully available, unlocked and ready. I can zoom in or out, move all over the maps with no problems. I can load a waypoint file and see all of the waypoints on the 2012 map ok.

Everything is fine until I try to select ANY map segment. Mapsource instantly opens an error box saying, "There is a problem with this Garmin application." It wants me to click on a button to copy to the clipboard, and send to Garmin. I cannot click on anything. Mouse still works, and the only way to get out is to use Windows Task Manager and End Task. This happened on both other computers, but the exact same version of Mapsource is still working perfectly on the computer which took the original download from Garmin. On both other computers, I tried going back to the Mapsource that was installed with the 2012 update, but I get the same error. I have also tried using Mapsource 6.16.3 patched, and get the exact same error.

Has anyone else tried to install 2012.1 on another computer and run into this problem? Perhaps a registry entry was made on the computer during the Garmin download that is not being included in the install on another computer? Perhaps I should try downloading the 2012.1 update to the new computer, installing only on the computer?

Any thoughts?

Thanks,

Howard
