no way to slipstream DX9. You have to use cmdlines.txt to initiate normal DX installation during windows setup. You have to use the /opk switch for quiet installation. I've attached a cracked dxsetup.exe which accepts the /opk switch. Rename the dxsetup.txt to dxsetup.rar I succeeded into slipstreaming several hotfixes, but not all of them. for integrating I use XPCREATE. this is the bes soft for the purpose IMO. The rest of the hotfixes I start from cmdlines.txt with these switches: "/Q /N /Z" dxsetup.txt
