Hello, I have gone out to the MSDN and dnloaded the latest copy of Vista Ultima w/SP1 intergraded into the image. I have also gone to MSFN and dnloaded the 1.1.6.RC to work on the SP1 image. Problem I am getting is: When launching 1.1.6.RC I am getting this message. vLite supports Windows Vista from version 6.0.6000.16386 (RTM) Version detected is: 0.0.0.0. You can continue at your own risk or if you just want to make/burn bootable ISO. Anybody know why this error is happening? bA
