I use windows 7 64 bit sp1 ultimate english. And winreduser 7 v 2.99.4.1 I have only 32 bit version of tools installed. All works just fine until i try creating an iso,it finishes but nothing in the folder. I tryed severel times. Most strange thing is that it worked with the former old version. I try the old one again but dont work anymore. Thank you anyway for trying to make a very cool program
