7z SFX Modified Module and Tools


Recommended Posts

I have a sfx extraction question. Does anyone know of a way to supress pop-up error messages and have them write out the cmd prompt or txt instead?


I use the sfx with automated deployments of unattended installs and every once in a while I get an install that hangs. Since the installs are being done under a deployment account, we can't access the desktop to see the error message. This makes troubleshooting hard and time consuming. So far the hanging seems to be typically caused by a locked files or an invalid path.


Example of extraction command:


mySfx.exe" -y -gm2 -InstallPath="C:\\mySfxPath\\location"


Thank you,

I'm trying to pass a parameter containing spaces when calling the installer, but it doesn't seem to work. For example :

installer.exe -! firstParam "C:\some path with space\test"

This is supposed to call a .bat file and pass it the two parameters. The .bat is declared as :

RunProgram="cmd /C \"%%T\test.bat\""

It doesn't work. It seems that as soon as there is a quote in the parameters passed to "installer.exe", then "test.bat" is not called correctly.


When I do not use spaces or quotes :

installer.exe -! firstParam secondParam

Then "test.bat" correctly receives "secondParam" as the second parameter!


How can I pass a parameter containg spaces? I've tried without success :

installer.exe -! firstParam "C:\some path with space\test"installer.exe -! firstParam \"C:\some path with space\test\"installer.exe -! firstParam \\"C:\some path with space\test\\"

Even that doesn't work :

installer.exe -! firstParam "secondParam"

Thanks in advance!

Well, I'll have to find what is different for me then!


I guess it has something to do with :

RunProgram="cmd /C \"%%T\test.bat\""



I'll check that tomorrow. Thanks for your help!

Ok, so when launching using params with quotes, for example :

test.exe -! firstParam "secondParam"

This works :

RunProgram="cmd /C test.bat"

But this doesn't work :

RunProgram="cmd /C \"test.bat\""

The problem is that I need to put "test.bat" inside quotes because it is, in fact, more something like this in my case :

RunProgram="cmd /C \"%%T\\some path\\test.bat\""

The workaround is to remove "cmd /C" completely and then it works :

RunProgram="\"%%T\\some path\\test.bat\""

I'm not sure if there is a difference when launching the .bat directly or using "cmd /C" though...

RunProgram="cmd /C \"%%T\\some path\\test.bat\""

In this line you want to remove unnecessary:

cmd /C



RunProgram="\"some path\\test.bat\""
