There is a plugin dir in this folder also (used to unpack the 7z files) we don't care… Plugins can easily be investigated by consulting the following website: In our case, we have System.dll and TvGetVersion.dll
PLUGINSDIR as the name suggests, is the Container Directory of these DLLs. NSIS also has a wide range of plugins to accomplish various installation tasks. Let’s examine the content by opening the executable with 7Zip application:Īs you can see, we have 2 Directory Entries: All that is needed is an archive manager like 7Zip. It’s pretty easy to unpack an NSIS Application. Now we need to study the structure of this package and carve out all its files. NSIS Files Extraction and Further File AnalysisĪs stated previously, the executable is delivered as Windows Installer, packaged and compressed with NSIS Technology. You can already see that it is a SFX archive. Additionally, you can see also the presence of a Resources Section and reloc section. Here is the Section Headers entry:Įntry Point belongs to. This mean that the application is compressed (Packaged) with NSIS (Nullsoft Scriptable Install System) technology, a professional open source system to create Windows Installers.įrom basic information, let’s now view more specific information about its PE Geometry. In any case, I know that a 7-Zip self-extracting archive can do what you want (it can execute a file after unpacking), and WinRAR SFX almost surely can, too, but as I said earlier, I'm not very familiar with it.File Information clearly indicates the Nullsoft PiMP stub. I don't know anything about that tool, but it would surprise me if Windows Installer can't create an MSI with lots of files. But none of these is an installer system.WinRAR (and other archivers) can certainly package all of your files into a single file.that's their raison d'être.but for building an installer (and, very importantly, an uninstaller), I use NSIS.Īfter writing the comment above, I looked at your files list and noticed that you did build an MSI with Windows Installer.my apologies. I've never used WinRAR to create archives.I use 7-Zip, as well as a third-party file manager with a built-in packer. "SFX" means a self-extracting archive, which WinRAR, WinZip, 7-Zip, and many other archiving utilities can create.
WinRAR is a file archive/packer/compression utility, along the lines of WinZip and 7-Zip.
