Windows 7 x64 .Net App Crash (works on everything else)

I'm working on a .net application compiled for "Any CPU". We have succesfully deployed the application to mutliple environments. The only one giving us issue is Windows 7 x64 (it is crashing immediately complaining for BadImageFormatException). When I run the application with Process Monitor attached, I get the following before it initiates Windows Error Reporting.

Has anyone else seen this?

As a follow up to Hans' point, check the following:

Essential part:

You need to set Properties > Build > Platform target to "x86". This will force it to run in WoW64, so the 32-bit mixed model Phoenix assemblies will load.
