I'm trying to unpack a NSIS setup.exe with 7-Zip 4.42. I don't have any problems when using the 7-Zip file manager, but calling "7za x setup.exe" gives "setup.exe is not supported archive".
Is there no NSIS unpack logic in 7za.exe? Why?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I've also had some similar issues, I discovered it was unpacking the files to where it had be called from, meaning that you might need to use the -o [output] switch to make it work..
Something like:
c:\7z.exe x -o c:\temp c:\downloads\setup.exe
Temp is folder where you want to extract files, and downloads is the folder where setup.exe is located. Don't forget to add "" to avoid issues because of spaces in paths like "Documents and Settings"
Hope this helps!

Hi!
I'm trying to unpack a NSIS setup.exe with 7-Zip 4.42. I don't have any problems when using the 7-Zip file manager, but calling "7za x setup.exe" gives "setup.exe is not supported archive".

What about reading the help file ?
According to the chapter "Command Line Version User's Guide"
7z.exe is command line versions of 7-Zip. 7z.exe uses other modules from 7-Zip package.
7za.exe is a standalone version of 7-Zip. 7za.exe supports only 7z, zip, gzip, bzip2, Z and tar formats. 7za.exe doesn't use other modules.
So if you want to use the command line, use 7z.exe instead of 7za.exe
Remark : 7z.exe uses the same plugins as the 7-Zip file manager.
