MSI patch files (*.MSP) can be applied to an admin image to properly extract its files. Another resource is this list of Installshield setup.exe command line parameters. It is a good reference for silent installation and other things as well.
#File extractor full
It is essentially an MSI with a custom, more advanced GUI, but it is also full of bugs.įor legacy setup.exe files the /a will do nothing, but you can try the /extract_all: switch as explained in this pdf. That's to run with GUI, you can do it silently too: msiexec /a File.msi TARGETDIR=C:\MyInstallPoint /qnĪ setup.exe file can also be a legacy style setup (non-MSI) or the dreaded Installscript MSI file type - a well known buggy Installshield project type with hybrid non-standards-compliant MSI format. Run these commands from an elevated command prompt, and follow the instructions in the GUI for the interactive command lines: Essentially it is either delivered as an MSI file or wrapped in an setup.exe file. You can perform an admin-install in a few different ways depending on how the installer is delivered. It is quite an important concept for system administrators, application packagers, setup developers, release managers, and even the average user to see what they are installing etc. Please read the stackoverflow post linked above for more details.
#File extractor install
In essence the admin install is important for: It is recommended to read more about admin-installs since it is a useful concept, and I have written a post on stackoverflow: What is the purpose of administrative installation initiated using msiexec /a?. All of these are handled correctly by doing an admin install. As to compression, there are actually three different compression algorithms used for the cab files inside the MSI file format: MSZip, LZX, and Storing (uncompressed). Always prefer to run the actual admin install over any hacky zip extractions. Note that running an admin install versus using a zip tool to extract the files is very different! The latter will not adjust the media layout of the media table so that the package is set to use external source files - which is the correct way. This ensures that the source files are always available for any repair operations. It is basically intended as a way to create a network installation point from which the install can be run on many target computers. This is called an administrative installation. MSI or Windows Installer has built-in support for this - the extraction of files from an MSI file. There is built-in MSI support for file extraction (admin install)
