I am trying to install the National Geographic Topo application on my 2100. I unlocked the device and it is working fine unlocked. I used Windows Mobile to link to the 2100 which seems to be working OK as it does copy the Topo application to the CE. My problem is that I am getting a message that Topo is not compatable with this version of CE 5.0 however Topo should run on CE 5x.
I also tried to install another application which copied over to the SD card installed in the 2100 but I was not able to complete the installation of this file either. The CAB file copied OK to the 2100 file but there was no option to complete the installation.
This leads me to believe that something is missing to complete the installation of CE applications on the 2100.
