It has nothing to do with the O/S but everything to do with the app you're loading the .DLL with.

You can NOT mix 32- and 64-bit code in the same process. So, if the main app is a 64-bit app or is compiled "AnyCPU" and running on a 64-bit O/S, it can NOT use 32-bit-only .DLL's.

Either supply a 64-bit version of your .DLL or recompile the main app, if at all possible, to be a 32-bit only app.

Yes, you can run 32-bit apps on a 64-bit O/S.

Allow application pool to allow 32 bit.
