wimboot appears to be causing a runtime error in app

What exe are you running, have you developed it yourself, or is it something available to others as well.
You should have more information and some kind of stacktrace, make sure you build with debugging enabled.

One thing that you should test is to start the same wim from directly from USB and default bootloader instead - I'm not surprised if WDS itself injects something.
