Hi Folks, I've got a tablet pc with my Original OS CD's -> yes, TWO cd's Anyways, i've copied both contents from the CD's to a single folder. the second cd has a CMPNENTS folder. in that it has TABLETPC, NETFX and MEDIACTR subfolders. i then slipstream sp2. all good. i then install the cd (burn to bootable cd, etc) and it installs fine ... BUT there's no tablet pc stuff (eg. virtual keyboard, etc). After doing lots of searching i found on the MS TechNet a post about a special product key that is required. If u have this TABLETPC product key then the install auto installs the tablet stuff from some tabletpc.cab file.... hmm. ok.. so i check the ORIGINAL cd winnt.sif and VIOLA! there's my product key in there. so i copy that key over to my own slipstreamed cd and .... ru-roh. i get ASKED for my product key. ok - so i'll manually type it in. WRONG! what?! WRONG. it rejects it. is it possible that my product key only works with my original xp sp1 tablet pc OS cd's and not with a slipstreamed sp2 version? if so, is there any way i can replace my OS cd's with some new ones with sp2 slipstreamed? it's very frustrating i have the originals and still i can't get it right. i'm very confussed.
