I'd say this is kind of inbetween both SuperUser and StackOverflow, but I am writing a GUI application using Qt that I would like to run within WinPE. I am well aware that WinPE is a very limited environment in terms of libraries and subsystems, but I would very much like to find out what prevents my application from running in WinPE. I've built the application for the correct platform (x64) and I've used the windeployqt-tool bundled with Qt to add dependencies. When I try to launch the application in WinPE I get no reaction at all. No error, no window - it just doesn't start. It works within a "normal" Windows environment.
Any suggestions to what I could do to find out what prevents the application from launching? I was thinking a debugging tool of some sort may help, as to see what library/subsystem the application is looking for?
