Thanks Aarron I've done some testing to, installing DX9 (patched) in svcpack.inf before 839643 and get the same result, patch don't apply. As Alanoll mentioned, I will try the slipstream with jdoebeck's batch, seem to be the best solution.
1st of all thanks for this forum, I've found a lot of answer there without asking any question. But this time I've got a question with no answer (not for long I'm shure) The new hotfixe for DirectX posted by Microsoft on the 8th is splitted in 3. If I would like to apply it on my current computer I need the one for DirectX 9. If I would like to apply it on my install CD, hotfixes are installed prior to programs so I need the hotfixes for DirectX 8 while DirectX 9 is installed after. I'm obliged to apply the specific patch for DirectX9 after or is there any other way to do something cleaner ? (I'm not using XPCreate yet) Any suggestion ?
