Yeah I already checked this out. And I must say.. hell of a job, man. Awesome work!

But man, the options are too much for me. I want to keep my repacks simple. I just want main repack page, directory page, installation page and finish page.. no autorun no lock window nothing. My script lacks extracted file, percentage, time elapsed and time remaining.
Another problem is I can't find any pzlib compressor here that actually works with my script. I tried Carldric's mini compressor for pzlib, it did make the archive but it shows decompression failed error.. even when I used his IS Done Support in the script. So currently I'm using Razor12911's Compressor v2.1 and it doesn't have pzlib compression method, and the only method I depend upon is srep64+lzma. Not a thing to tell you that it seldom gives a good output.
I'd really appreciate if you can add the above options on installing page and pzlib support to my WPI that I've attached. It'd be a piece of cake for you.

And please.. please do suggest a good pzlib compressor that will work for the options you add. BIG THANKS in advance.
