I am porting an Win CE 6.0 app to a new hardware.
The app doesn't start on both WIN CE 6.0 and WEC 7 on the new hardware.
But if you first re-install the NETCFv35.wce.armv4.cab over the existing installation (force installation) then run the app, it starts both on WIN CE 6.0 and WEC 7
Every time after a reboot the NETCFv35.wce.armv4.cab needs to be re-installed to start the app.
I can also debug the app from VSTD 2008 which actually gave me the clue to deploy the NETCFv35.wce.armv4.cab at the very beginning.
Thanks in advance for your cooperation.
Found the solution. The NetCF framework was not a part of the OS image and had to be installed later. If it were there would be no problem.
