With no information on why you're not satisfied with your script it's impossible to point on specific elements (unless I go to buy the program only to help you - not gonna happens).
Also you make zero effort in putting comments in your script so any one reading this have to guess.

So my suggestion to improve your script is this:
1. Add commentt. Make sure that anyone reading your script know what you're thinking on. Something not working as expected - then describe it.
2. Use pastebin or similar service that provides syntax highligting for programming languages (I think there is one code format at this page for bat scripts too).
3. If the installer deals with dialog boxes, you probably want to use Autohotkey instead, because it allows you to do mouse clicks and other useful things you just can't do with bat scripts.

Agree with Grobe - especially the need to comment the script.

And although English may not be your native language work on the grammar and syntax of the "echos". Need to be correct and consistent. Doing so will help both you and the intended end-users.
