I am trying to decompress a NSIS executable. With the GUI version of 7zip I am able to do this and the exe is listed as: 

Type = Nsis
Method = LZMA:25
Solid = +

With the command line version 7za I am unable to do this, but it is strange, since it is possible to compress with 7za using -m1=LZMA:d=25

Any idea to decompress or any alternative to 7za?

There is a separate different portable version of 7-zip by a third party. http://portableapps.com/apps/utilities/7-zip_portable

This one can be put on a USB drive and the 7z.exe can be used much like 7za.exe, but it is able to cope with NSIS exe files.

I also found that, after installing the standard 7-zip from http://www.7-zip.org, one can grab and put 7z.exe and 7z.dll in whatever directory and s/he has her/his own light but full fledged command line version of 7-zip.

Pity that there is still to go with the main file plus the dll. Instead 7za.exe has no dependencies.

If you know of a static linked version of 7z.exe (no dll) or a trick to make a single executable out of them, please let me know.

cheers
