Yeah, do as Jaak said.
This is drivers-only, for any add-ons packs, either use nLite along with an add-on maker or some pre-assembled pack.
While .NET certainly is a requirement for ATi's CCC to work, the size of it would exceed the DriverPack Graphics A, which looks a bit rediculous, IMO.
Also, the version of DX9 that comes with XP may not be up-to-date anymore, but I think all drivers still work with it (whether or not a specific programme works is a different question, but that is none of our buisness so to speak).
Again, it is pretty huge in size, plus there are numerous already existing DX add-on packs available.
EDIT:
Nice auto-double posts going on here.
If I delete one, both are gone, if I repost, both re-appear.
Oh well...
*sigh*
