MUI_LANGUAGE 'French' Section 'Extract makensis' SetOutPath $INSTDIR File. 7zip can extract files from [certain] NSIS installers but it cannot insert new ones. NSIS has specific structure and it is sophisticated system not only simple archive. If you have script for an old installer that simply add new file to it.
Contents • • • • • • • • • • • • • • • • • About Currently NSIS installers cannot be fully decompiled. The installer itself doesn't provide any method to extract files or the script without installation. It is the developer's choice whether the source code and/or the files for the installer are available to the public or not. Extraction Tools There are, however, external tools that allow this: • Since version 4.42[may 2006] supports decompressing NSIS installers. Since version 9.34 [Jun 2014] 7-zip is also able to extract the compiled scriptcode. • The decompression plug-in InstallExplorer is also available for TotalCommander. Beside the files it'll create the file 'script.bin' compiled scriptcode.For use without the TotalCommander the is a good option.
Well since [Feb 2014] InstExpl suffers from problems naming file names and dirs correctly that were created with NSIS 3. That's because the implementation was slightly changed so names like $INSTDIR, $PROGRAMFILE.
Inside strings are not expanded correctly. Decompilers • Since version 9.34 [Jun 2014] ] it'll extract *beside the files of the setup* the compiled script code to a file named [NSIS].nsi • or NSIDis NSIDis is a open source Python script that'll help you to nearly fully recover your NSIS-installation scripts.
Its state is currently alpha - and so not very user friendly and stable. • NRS is a set of Python librairies used to unpack and analysis NSIS installer's data. It also has an IDA plugin used to disassembly the NSIS Script of an installer. • Protection against Decompilers As a general note to software developers, you should use a plugin like if you need to protect certain files in your installer.. Or if ya in the mood for compiling the NSIS have a look into nsis-3.xx-src Source exehead fileform.h. Mixing up the order of the enum with all the EW_* a little bit as recommend in the Comment.
It will mess up decompilers output that expect these tokes to be in the standard order. Or shift or enlarge the.reloc section in the PE-header by 0x400.

How to extract MSI files from an EXE installer Problem: You need to extract an.msi file from an.exe installer. Solution: There are at least three ways of solving this problem, but none of them is universal. You might need to go through all of them to find the one that works for the EXE installer that you have. CodeTwo strongly advises against extracting (and using) MSI files from the EXE installers of the CodeTwo software.
Unless the product website allows such an operation (or unless you are instructed/allowed to do so by ), use the.exe setup files. The first method is based on the fact that most installers extract their.msi files to the temporary files folder during the installation process. To extract an MSI file from an EXE installer, you need to: • Launch your.exe file. • When you see the first prompt (e.g. A question about whether you want to continue installation, accept a license agreement, etc.), do not click anything in this window and do not close it. • Open Windows Explorer, type%temp% in the address bar and press Enter. • Sort the files in the folder by the modification date.
The newest file on the list should be the.msi file you are looking for. • Copy the MSI file to a safe location before you close the installer prompt window (see step 2). Be aware that if you close the installer window, the MSI file will be immediately deleted from the temporary files folder. The second method uses a free third-party tool called 7-Zip to browse the content of the.exe installer file.
Follow the steps below. • Download 7-Zip and install it. • Right-click on the.exe file (from which you want to extract an.msi file) and from the shortcut menu choose 7-Zip > Open Archive. • Do not extract any files yet. Instead, browse and look for the folder MSI within the contents. It might take some time to find this folder because it is not always located directly in the root directory (its location may vary depending on the installer). • When you locate the MSI folder, you will notice that it most likely does not contain any.msi files, but a file or files with no extensions and rather cryptic names such as 132.
