I got the same error on several hardware. So I tried to use a new installation of my vista x86 ultimate (version 6.0.6000.16386) without sp1 and without any virus-scanner exept the vista defender. I installed the newest waik and the vlite 1.2 beta. i have about 20GB free on my working drive. the slipstream fails with the error "Failed. No changes were saved". i used a german vista x64. is there any idea, where the problem is? greetings LaLinea
