Some suggestions:

* Try loading your DLL in Depends (from the Windows SDK) on XP. That will show you if there's a dependent DLL that's not preset on XP.

* Run fuslogvw.exe (part of the .NET SDK) and look for entries related to your Clarion app. It's possible that the .NET loader (fusion) is logging a more meaningful error when your assembly (DLL) is loaded.

* Check the OS event viewer logs. I've had stack traces show up in there sometimes when things aren't loading.

* Try writing a simple Win32 C++ app which loads your DLL and calls a dummy entry point to be sure that it's loadable *at all* on that OS. If not, it's probably a dependency issue like I mentioned above. If it's loadable then clearly it's an interaction with the Clarion app.

* Load your DLL project in dev studio and set the Clarion exe as the debug exe and check the boxes to break for All exceptions under Debug > Exceptions... when the load fails, is there any first-chance excetion triggered preceding the failure? (this one's a long-shot)

* Try using Procmon from sysinternals.com and monitor disk activity. Set the filter to include only you exe process name to remove lots of unrelated output. See if there are failures reported before the DLL load fails.

* Does your exported function happen to call code from another C# assembly you've created? If so, the related assembly may not be getting located properly as .NET searches in the .exe directory, not in the C++ DLL's directory. The first function using a type from the C# assembly can fail unless you've handled the AppDomain.AssemblyResolve event.

Good luck,
John

ps. I used Clarion back in 1990 or so...was DOS-based then. Wonder if its the same thing.
