Currently NSIS installers cannot be fully decompiled. We understand the need for secrecy of source code in many modern programs and thus NSIS does not store any code in the installer that can be completely decompiled back to the point where you have the original script. It is the developer's choice whether the source code for the installer is available to the public or not.
7-zip (version 4.40beta at the time of this writing) supports decompressing NSIS installers compressed with LZMA, but the source code is still partially compiled and requires extensive modification before the script can be compiled by MakeNSIS.
A (de)compression plugin is also available for TotalCommander.
As a general note to software developers, you should use a plugin like DCryptDll if you need to protect certain files in your installer.
