ProRAT Help

Hi guys,
Just registered here. I want help in installing the new ProRAT release(ProRAT *.* Fix2) which I had downloaded from the ProRAT website.
My problem is, after unzipping it, there are * files and one folder displayed.
2 are help files(in english and turkish, respectively). The third is an executable that says ProRAT(It does not have an icon image).
The folder is a collection of the languages used by ProRAT.
Now when I click on ProRAT.exe, my system says that access is denied.
I'm running on XP Professional SP2.

Thanks for your time,
Cyber Punk
