Can't find PInvoke DLL 'Mpr.dll'

Question

Hi All World Experts,

I am developing a .net 2.0 windows form application for a mobile device like scanner (Intermec CK3). The application is running fine on my windows XP. But when I moved the application to the scanner (Windows CE 6.1) and ran it. I got an error like "Can't find PInvoke DLL Mpr.dll". I seached for the dll on the scanner and could find it. The dll is on the windows XP.

Could you tell me what I have done wrong in my  codes?

Any help would be appreciated.
