Same parametrs: vLite 1.2, WAIK SP1 under XP SP2 and Vista SP1. Please excuse my basic information, but maybe it will be helpful for someone. So I vLited Vista SP1, and whole process was successful, with no error. After that I wanted to try my ISO, so I mounted it with Daemon Tools. And I got an error, immediately at the begining of installation of Vista, exactly when system cached files from medium, (before first installation window "please enter your serial" ...). I burned my ISO on DVD and got same error. Error log says 0x000000..., not enough system resources or something like that (processor, RAM, disk space are OK). I suspected Daemon Tools. I uninstalled it, restarted PC and made ISO with exactly same configuration like the one with error. And without Daemon Tools it worked fine, no harmfull problem. Is there any known relation among vLite, Vista and Daemon Tools?
