yes there a few threads to read for a wealth of info.
The first program is called Freearc ( which may but not always be used in inno scripts ) >
Code:

the second of course is Inno itself-I'd suggest unicode as most scripts here use it, not all but most.>
Code:

First one of course as your using yeners scripts>

When you read the second link above, pay attention to the link inside as it points to where you ask questions if you have any. But i'd suggest to read each thread thru entirely & make notes for questions you have ( see if they have already been asked & answered before )
last one is for of course the script thread, which has a bunch of info in there too.
