New Post: MapWindow on x64 systems

ok here is where I am at. this is a custom application using the ocx as a map control plus some of the utility DLLs.

Developer machine:
Windows 7 x86
MapWindow 4.8.6 (Final Release) x86
Visual Studio 2010. Compile the application against the .NET4 Framework.
Case #1: Compile against AnyCPU.
Case #2: Compile against x64

Target machine:
Windows 7 x64
The user is the admin of the machine.
All .NET Frameworks installed all the way up to .NET 4.5. He's also a developer so he has Visual Studio 2005 through 2012 installed.
Installed MapWindow 4.8.6 (Final Release) x86 and tried both cases above. Both crashed.
Uninstalled MapWindow 4.8.6 (Final Release) x86 and installed Installed MapWindow 4.8.6 (Final Release) x64. Tried both cases above. Both crashed.
The only error message we get is the "Application has stopped working" message before any part of the GUI is displayed. We then get the option to send information to Microsoft about the crash.,
The MapWindow application itself works.
