I have the following command in the cmdlines.txt file:

"%systemdrive%\Install\HotFixes\KB839643.EXE /Q /O /N /Z"

and I am getting the following error

Setup was unable to invoke external program %systemdrive%\Install\HotFixes\KB839643.EXE /Q /O /N /Z because of the following error:

CreateProcess returned error 2 (2).

Any suggestions?

i think there's another topic about this hotfix already...

some quotes from that topic

DirectX90-KB839643-x86 is the update for directx 9.x only , WindowsXP-KB839643-x86 is the update for directx 8 which is included in an xp default install

From RunOnce, or similar, no problem

so... lots of people have had difficulty installing this update through svcpack.inf and cmdlines.txt by the look of it...

just install it through RunOnce

ad this to cmd:

ECHO.

color 0f

ECHO Installing DirectX 90 Security Update

start /wait  %systemdrive%\install\hotfixes\directx90-kb839643-x86-enu.exe /quiet /norestart

put het hotfix in:

$OEM$\$1\install\hotfixes

and edit this in winnt.sif if you dont have it ad the bottom:

[GuiRunOnce]

%systemdrive%\install\hotfixes\hotfixes.cmd

@ jp2002:

I hope I'm assuming incorrectly here, but if that command is actually a line in cmdlines.txt then there's your problem.

Putting that command in a batch file and have cmdlines.txt call the batch file should work.
