dependency DLLs don't appear to work on Windows 7 x64

[GoogleCodeExporter]

I've compiled my application using Microsoft Visual Studio 2008 (sp1) on 
Windows 7 (64bit).  I get the following error when I try to add a port 
mapping:

An attempt was made to load a program with an incorrect format. (Exception 
from HRESULT: 0x8007000B)

on line 400 of TCMNATPMPPortMapper.cs which reads:

     r = NATPMP.initnatpmp(ref natpmp);

As further information, the "Port Map 1.0" example application also fails 
(not sure what the error is, but I assume it is the same problem).

The two DLL files and the oui.txt file are in the bin/debug directory with 
the EXE and the latest were downloaded today 12/01/2009.

Any suggestions?

Thanks,

Ross

Further, the application works correctly on Windows XP (service pack 3).

I'm running 32 bit and I was having tht esame problem with that DLL not 
loading. I 
changed it to AnyCPU config and it worked just fine.

Yes, I confirm that error. The program crashes immediately in Win7 x64.

Is this project alive anymore? This really ought to be a much higher priority, 
as they don't bloody make 32-bit processors anymore.
