Windows Installer doesn't support temporary files. So I assume you are simply installing some files and deleting them when install ends. This is not a good approach because for Windows Installer they are basically missing resources.
While must of what Cosmin has answered is true, he doesn't seem to be aware that InstallShield has a feature called Support Files that already does everything he describes. Drag some files into Installation Designer | Behavior and Logic | Support Files | Language Independent and InstallShield will automatically stream them into the ISSetupFile table and sequence custom actions that extract the files to a temp directory during the install and clean up the files at the end.
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.
