You can try using a Remove File operation to delete your application files and RemoveDirectory function (in a custom EXE for example) to remove the folder. The custom EXE can be added as a custom action and it can read the install path from the registry or a configuration file (it depends on where you want to save it during install).
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.
