a genuine one i ve to install the hotfix via svcpack because i wouldlike to install the net frameworks using the Silent .NET Maker who make a silent installer via svcpack. this is the second unattended windows cd that i made, and the first time (about 6 mounth ago) the svcpack method was working! so, i must made a big error, but i can't find it! LOL maybe i must install the hotfix in another way, and install the frameworks via runonceex thanks again ^^ p.s: i lost the source of the first unattended xp, so i m not able to compare the two source
