7zip extraction doesn't run

[N30M0D]

hi, guys

I cannot understand why 7zip doesn't perform an extraction during an unattended installation in a script invoked by :

[GuiRunOnce]

%systemdrive%\install\start.cmd

I've copied 7za.exe in the same dir of the .7z package typing the command "7za.exe x archive.7z" but nothing happen. I must put other files together with 7za.exe? a .dll? Or it doesn't work in that specified stage?

Thank you, bye

don't forget the -o option:

7za x archive.7z -o C:\OutputDirectory

[N30M0D]

I don't need to write -o C:\OutputDirectory because 7za x archive.7z extract files and folders in the current dir. Then I can start the install file. If I run "7za x archive.7z" or "start /wait 7za x archive.7z" and then the next start /wait operation all works fine (under xp). But during an unattended installation does't work.

an input?

hhehehehe

why dont u do yourself a favor and download the latest beta

www.7zip.org

Why not make a selfextracting archive. You can do this with the windows version of 7z

@astalavista

I've tried with latest version (beta) and nothing is changed

@colinbate

I've tried to make a self-ex with winrar but seems it doesn't support /wait ;

7-zip support it? And what switches I must use?

[Astalavista]

pls open the help me file of 7zip everything u keep asking is in there

[N30M0D]

I would be grateful if you can find what I'm looking for in that file

[Astalavista]

In parameteres line I have to type in "application.exe /switches" and stop? Or I have to add other things such as overwrite=2, etc.? I need to know here if 7-zip self-ex support /wait (in an unattended stage) because each attempt cost me a CLEAN INSTALLATION!

[N30M0D]

Problem solved after hours & hours of clean installations and many attempts;

If I make a .cmd which contains:

start /wait 7za.exe x archive.7z

start /wait an_application.exe /switches

and so on...

all works fine If I am UNDER XP. Instead during an unattended installation,in a script invoked by this (contained in the winnt.sif file):

[GuiRunOnce]

%systemdrive%\install\start.cmd

I MUST type:

start /wait %systemdrive%\location\7za.exe x %systemdrive%\location\archive.7z -o%systemdrive%\OutputLocation

start /wait %systemdrive%\location\an_application.exe /switches

7a.exe, archive.7z and files extracted are in the same dir.

because I've also tried this before:

start /wait %systemdrive%\location\7za.exe x %systemdrive%\location\archive.7z

archive.7z should be extracted in the same dir. Extraction window appear and list of files extracted too but It seems that files aren't phisically extracted! In fact the extraction dir not contains them.

Hope it be useful for someone.

Now I can Install a version of .NetFramework 1.1 with sp1 slipstreamed in .7z format (for example).

because each attempt cost me a CLEAN INSTALLATION! 

OUCH!

That's really sad. Why not use VMware to test your uA installs!
