i have been trying to install it without any luck at all.
i got just an error message with and "Ok" Button when i try to install with this command:

rundll32 syssetup,SetupInfObjectInstallAction DefaultInstall 128 .\AC3ACM.inf

it comes in two files: AC3ACM.acm and AC3ACM.inf
i call it from runonceex in the hdd with a cmd file with the above command. the cmd file is along with these two files. i dont know how to install it. anyonw can point me out on this one?

thanks.

I know it installs from the desktop with a rightclick on the INF and choosing install.

For unattended installation, get the AC3ACm.acm file into system32 using whatever method is easiest for you and apply this regfile either using cmdlines.txt or svcpack.inf


Dont forget, reg files need to end in a blank line.

wiil it work if i make an installer (msi) that copies the acm file to system32 and then import those reg keys to the registry.

i want to use it from runonceex. thanks for the help.

i will make it meanwhile to see if it works with an installed copy of windows.

The above pretty well describes the codec pack i offer in the stickies section.

i appreciate your cocec pack but i just install some of the components in there so i make some installers of my own. the only thing im missing is the ac3-acm decompressor...i just finished my installer for it...will test it and post if it works.

thanks.

Go to the Run box and type "iexpress". IExpress has support for INF file installations and will pack your files into a SFX archive.

i use this command via RunOnceEx

REG ADD %KEY%\028 /VE /D "AC3-ACM Decompressor 1.31" /f
REG ADD %KEY%\028 /V 1 /D "Rundll32.exe Setupapi.dll,InstallHinfSection DefaultInstall 132 %SystemDrive%\install\Codecs\AC3ACM.inf" /f

never thought of the venerable iexpress. thanks for the reminder. i already pack it and it worked well.
thanks to all for the other advices.

Yeah, thanks for this great tip!!
