Well Dougiefresh, first of all i love your work :wub_anim: and hats-off to you.Now regarding my problem i am also facing the same kind of problem as Mtek01 is facing.I have also nlited the xp by slipstreaming service pack 3 and if i want to integrate your Xptsp GUI v1.4.6.0 or any previous build iam getting the same error as (The selected folder does not contain the xp installation source files).I am running vista, i think under vista patching is not working.Please help me. In my previous post i requested for adding ubericon effects, thanks for accepting my request and sorry for using all capslock in my previous request. This time also i want to request you for some new features in your pack, as i love your pack and i wish that only if possible please try to add Welcome Centre for xp like vista, Fast aero, Windows_7_Property_Dialog_4_XP_by_pri2sh.Once again please accept this request if possible, i think others will also love it :wub_anim: . Thanks and keep going your awesome work. :thumbsup_anim: Regards, Manikant. Sorry for double post it happened accidentally
