Hi all, I'm a bit new with this great product and require your assistance in two little issues.

1* I'm trying to create a patch for a computer game by the help of SetupBuilder. All seems good for now but I don't want my installer runs, if this game is not installed in that pc. Before starting, it must check that is this game installed or not. How can I make it?

2* And I want to make the installer find where this game is installed. It must find the installed directory and patch it without question about where to install. Could you please help me about these subjects?

Thanks in advance
