This is more a redirection than an answer. One thing you need to be aware of is that PowerBuilder produces executables that do not follow standards for Windows executable files. Essentially they are a bootstrap routine to load the PowerBuilder virtual machine, plus a collection of class definitions (objects).
The cases you've brought up are not the first I've heard of where utilities meant to modify executables don't work on PowerBuilder executables.
If an external manifest doesn't work, then the manifest information isn't correct.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
