'System.BadImageFormatException' occurred

Bryan

Hey everyone. I'm hoping you can help me. Currently I am developing a media player using MCI and C#. The project has been worked on on XP 32 bit, Vista 32 bit and Visa 64 bit. It works fine on the 32 bit systems, however when I try to load the media file on the 64 bit computer I get an unhandled exception. It was:

An unhandled exception of type 'System.BadImageFormatException' occurred

Additional information: is not a valid Win32 application. (Exception from HRESULT: 0x800700C1)

Please help me fix this problems. Its being developed using VS 2008. Thank you.

Accepted answer
from the error you specified it seems like you just need to change the build type from any cpu to
x86

this will build it to work with dlls compatibility mode to win32 even on 64bit computers.

it should solve your problem...

hope this helps
