I have a ClickOnce (C#, WPF, .NET 4.5) application, it runs and works fine under Windows 7 32-bit. It is compiled as Any CPU.
Under Windows 7 64-bit I see the ClickOnce start screen, and then nothing happens (no errors, nothing obvious).
In order to debug, I have copied the EXE file and all relevant DLL files into one directory. I started from there: Again same situation, it runs under Windows 7 32-bit, but nothing happens under Windows 7 64-bit. I have crosschecked with a "clean" Windows 7 32-bit, and it is fine there as well.
.NET 4.5 was / is installed on any machine I have tested with.
How can I overcome / debug the application? What do I need to do make it run under 64-bit?
Event log under APPLICATIONS shows:

According to here, I could force building as a Win32 application, but is this the right way to go? The application is pretty simple, so I doubt this should be required.
Follow up, about the remote debugging: Visual Studio 2012: Can I start a .NET 4.5 application in a remote debugger (and not only attach)?
The first thing I did was updating the two external (Syncfusion) DLL files to their recent version. It was still crashing, but now I got an additional .NET event in the event viewer. I thought it might be "Syncfusion"-related, but the whole trace does not show any Syncfusion libraries.

Next thing, in the Visual Studio 2012 build, I checked Prefer 32-bit, this compiled exe runs on Windows 7 64-bit. So it is partly a success.
