Cant install any of the Apps

First I installed Aqua Control on my Windows XP Prof. SP 1 and it installed fine. But than when I try to install any of the other apps the computer freeze at the moment when he change for previous versions of the application!

I have no other signification problems with my windows XP. I use Y´s Dock, Y´s Toolbar and Stardock Objectbar.

Any help are welcome!
