Exporting function from an .exe to be used by loaded .dll

I have the following design.

Build host appname.exe that exports some useful functions. When I
compile this, appname.lib is created with the exported files.

Create plugin dlls that link with appname.lib and are loaded at run
time by the host appname.exe using LoadLibrary(plugin_name). These
plugins can use all the functions exported by appname.exe.

I have this design coded and working flawlessly on Windows XP. Using
the same code base I then created my CE.net version in EVC4. When I
run appname.exe on CE (in the emulator - no hardware yet) the plugins
do not load and GetLastError() returns 193 - Bad EXE Format.

I can't figure out why this is happening.

As a test I created a simple .exe and simple .dll in EVC4. The exe
exports one function and the dll uses it.

The dll load failed with the same error but as soon as I remove the
exported function from the exe and its reference from the dll it loads
fine.

This design is critical to my application - any help is appreciated.
