Inno Setup Questions

I've noticed there is a beta version of Inno Setup 4 which has Inno setup extensions integrated.

I've used the basic Inno Setup in the past and I am confident with using it (without the extensions). However with the new release it gives me extra options I want to use but I'm having more trouble working out how everything fits together.

Basically I need to be able to do the following, can someone tell me if it is possible firstly, then either point me in the direction of where I can find more info about this or even better give me a head start with some example code.

1. Check if Adobe Acrobat is installed (checking for a registry entry) if it is go to 2 otherwise launch a separate installation program and wait for it to complete.

2. Check to see if my application is installed (again checking the registry) if it is quit the setup program otherwise go to 3.

3. Install the program (I have a script to do this using Inno Setup) when completed add a registry entry for the program.

4. Quit the setup program.

If anyone can help I would appreciate it.

I have to agree. I would certainly like to see a bit more on the home page. Screen snapshots, examples, and step-by-step tutorials.
