x86 console application doesn't run on 64bit machines except in debugger

In order to get a better hold on my question NUnit: Could not load file or assembly 'some.dll' or one of its dependencies. The specified module could not be found I tried to reduce complexity by getting rid of NUnit. Now I wrote a plain console application (C#) which interacts with a c++/cli wrapper which does calls on company framework c++ dlls.

Dumpbin says that all assemblies are 32bit. Visual Studio has console application and wrapper set to x86. On x86 machines console application works like a charm, on x64 it doesn't, except when being called from my Visual Studio 2013 with debugger attached (doesn't work when run from Visual Studio without debugger). The assembly is set to "Systemeigenes Codedebugging aktivieren" (activate native? code debugging) and Visual Studio hosting process is deactivated. "It doesn't work" is represented by something like this:

 SetUp : System.IO.FileLoadException : Could not load file or assembly 'The_Wrapper.DLL' or one of its dependencies. A dynamic link library (DLL) initialization routine failed. (Exception from HRESULT: 0x8007045A)

I tried profiling with dependency walker (x86 version) on the 64 bit machines, but it dies after loading IMM32.DLL. The output on a x86 machine is like this:

When the wrapper is used by the software product I am actually developing (x86, C# WinForms) it works on x64 even without debugger, but only on my development PC.

What am I overlooking? Which tools might help me?

Am a little embarassed, but will share anyway:

The company framework library which I added to this existing project uses Jungo USB Driver. For unknown reasons the file wdapi1020.dll was checked in and copied to my bin directory. Unfortunately it was the x86 version of the file. When I finally figured out that I have to remove it, the PlainConsoleApplication used the one from SysWOW64 and everything went well. Now I have to convince either our admins to install the driver on the buildserver or the framework developers to change something about their usage of Jungo driver .... it will remain interesting.

For the ones interested, here's how I found out: I took the software product mentioned at the end of the question and installed it (instead of copying it from bin folder). When I put the console application into it's folder it suddenly worked. I started comparing the files and figured out that there is actually one too much. Removed it had a biiig smile on my face.
