Can anyone tell me how i can do one or both of these things to my installer repo I'm working on.

1: How can I get the same file to install two different places?


2: How to make your download say "Must install ....... First" and have it cancel the installation?

If anyone can tell me how to do this i'd really appreciate it oh and the repo i'm working on will contain cracked versions of about 16 different games in the appstore including Crash Bandicoot Racing and Super Monkey Ball.
