Thanks for the response MagicAndre1981. Problems solved by the following method. 1. Old HD, format and install vanilla Vista. 2. Install WAIK and vLite. Reboot. 3. Open vLite. Says install WAIK and hit install to get wimgapi.dll into root folder. Hit install, doesnt work! 4. Manually extract and install wimgapi.dll to root folder and viola things start working properly. 5. Complete intergration of SP1 and copy .iso to desktop. 6. Burn DVD and test on reformatted same old HD- works 100%. Next effort is to use more of the vLite options available and remove a heap of pre installed crap. A great little program (now!) Thanks very much Nuhi for all your work. Makes us lesser mortals feel a lot better to be able to some of the things you experts can do. (At least THINK we can!) ross
