Hi, I have official Vista Ultimate x64 DVD without SP1, I just want to add SP1 with VLite 1.1.6 beta 2, I just check Slipsteam SP1 and Creat ISO. My question is, I have integrate SP1 with Slipsteam tab, but after that "Apply" button is not available (grey), and If a Create ISO file, just after the ISO File creating "Apply" will be available, and I could do Rebuilding step (LOG Tab). It's strange because I have already create the ISO before Rebuilding... I repeat, I want to slipsteam only SP1 x64 into Vista folder, I don't want to Rebuild, I just want to keep full DVD. LOG tab is not useful for me ? I could use only Task--->Slipsteam---->ISO Tabs ? Thanks for your help.
