R.i.m.s.k.y., большое спасибо! Все получилось, однако есть еще одна маленькая проблемка:
Как вы и сказали доп.софт (DirectX, GameSpy Arcade) я положил в папку "Redist" с игрой. Сделал репак, но после установки экзешники этого доп.софта дублируются еще раз в корневой папке с игрой. Что надо изменить в скрипте, что бы это избежать?
Вот скрипт:
Код:

#define MyAppName "World Championship Snooker 2003"
#define MyAppVersion "1.0"
#define MyAppPublisher "BlackInferno"
#define MyAppExeName "WCS Real 2003.exe"
