I need a help with inno setup

Hello guys

I am having a problem when I install my system on Windows Vista.
I need to give all rights to the user on the folder of the system and this has being my problem.
In the main folder, the system needs to create some files when it runs, but the windows vista
doesn't allow it. Then I need to access the folder, on the security property I give all rights to the
user and the system works fine.

Please, take a look at code bellow so that you can see if I am giveng the correct form the rights on the folders.

Thanks very much
