Net Compact Framework -- Not valid pocket pc application

[acinarab]

Hello everybody.

I am using Visual studio 2003 to develop an smart device application for pocket pc ( Symbol ppt 2800). I developed my application . but when I deploy it pocket pc and click on it to run it gives an error like "Not Valid Pocket pc application".
on the other hand it runs correctly in emulator.
(it copies the x86.cab files to emulator but copies arm.cab files to device)
I could not solve this problem.
Any idea, help would be appreciated.
thanks

Did you see the application was moved to the pocket pc? check the "program files" in ppc.

I solved the problem by Hard reseting the pocket pc.
I could not figure out the situation but :)
