It seems not really possible, so I used Custom action instead. The trick was adding my custom action both to Install and Commit phases, though it only searched for file in Commit phase. If it is added only to Commit phase, then I got "MyInstallHelper.
InstallState not found" error.
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.
