Pocket PC 2002 & 2003 compatibility issue

[ppda]

I wrote a program using C++ for Pocket PC 2002 and its been working fine but when I tried to install it on Pocket PC 2003 it doesn’t work, it would say this application is not compatibil with current OS… is there a major difference between two OS?

I know there is eMbedded Visual Basic runtime for Pocket PC 2003 but I didn't write the app with visual basic. Any suggestion.

Many thanks in advance.

When are you seeing this message? I know that when you build a CAB install you have to specify the OS version, and if you don't put in the correct version range you will get that message when trying to install. Does this occur when you run the executable on the device?

Did you use MFC, this is an area that I understand has changed such that you will need to recompile your code in eVC 4 for it to work correctly.
