yeah, you can make pretty decent installations with winrar. i have some games in my unattended cd that install into program files, add a shortcut to the start menu, and execute a reg file to input the username and serial. haven't got a clue, but why would you need to use that! winrar has totally converted me, i haven't installed winzip, winace, etc for years now.Perhaps... but 7zip has better compression! And a 700 MB CD is quickly filled...
