I tried a few times, I have downloaded the Windows6.0-KB936330-X64-wave1.exe file from M$ website, still it gets like to 75% of the process bar and it just locks up there. I disable my AV (Kaspersky Internet Security) and with all the programs closed, it just sits there and stops from closing the process. I waited even 3 hours to see if it finished asp, but nothin. I have Vista with all the updates (apart from the SP1 that was released 2 days ago for Italian Enterprise edition, but with the same KB number, and yet couldn't be bothered to install it) and I am running the process from a laptop with Centrino dual core and 4gb of ram. I easily splitstreamed SP3 on XP but nothing to do with SP1 for Vista. Any clues? I saw that post about downloading WAIK or some stuff, still I had the 1.1.6 and installed the 1.2 over it, so there shouldn't be need. A note, at the beginning when it says it should install some stuff to run Vlite correctly I click on the lower choice (the only one I can click on), and it opens Vlite without any problems right after, without letting me install the upper choice. Could that be a problem? Thanx for any help!
