it can't work directly with ISO files, you have to unpack them with winrar, or mount them using daemon tools, and copy the files to say C:\VistaDVD\ , then point vlite at that the best way to learn is to just 'do it' yourself mate also, testing in a virtual machine saves you formatting your pc, use virtualbox, its free and fast. just remember tick what you want to remove not what you want to keep , just read the descriptions for each one and decide for yourself -for now, i wouldn't bother messing around with custom install screens etc, it's a waste of time
