I got this error when installing Vista SP1 made with vLite 1.1.6 Final: http://img73.imageshack.us/img73/2553/vliteerrortb6.jpg I got curious, because I had ripped off atleast 99% same things with 1.1.6 RC without getting that error, so I decided to do a little test. I uninstalled Final version and installed RC back. Took a clean Vista SP1 image and ripped it apart, installed in virtual PC and worked fine. Then I did the exact same thing, with the exact same last settings.ini file to the exact same clean Vista SP1 image, and it gave me that error, again. Also with vLite 1.6.1 Final I've experienced these things that didnt happen in RC: - I didnt get this screen with vlite rc, and if I remember wrong and I did get it, it certainly didnt took as much time to finish than it did with vlite final http://img73.imageshack.us/img73/3507/vliteerror2ls5.jpg - I didnt get this screen either with vlite rc http://img230.imageshack.us/img230/8016/vlitetq7.jpg Did I do something wrong, or is there something wrong with vlite? I've attached last settings.ini file to this post so someone can take a look at it, if they want to. Edit: I'm running Windows XP Professional x86 with SP3, if its relevant Last_Session.ini
