For most games you can skip the pre-setup by deleting the installscript.vdf file before the launch. But some games use pre-setup also after launch. For example GTA 4 checks the Rockstar launcher setting, where you need to perform some actions that are hidden by the first window. This makes it impossible to start the game.
