Extracting Files from MSI Installers

Sometimes you need to extract one file from an MSI file. A typical example is when you need just one DLL in order to make a project compile, but in order to get it you need to download and install a complete application. The ideal solution is to get the DLL file from the MSI file without having to perform the installation.

Some installers allow you extract the files to create a network installation. This is normally done using the command msiexec /a . Not all of them extract all the files, though.

Well, there is a small utility hilariously called Less MSIérables that allows you to extract files from msi installers. It works great – it has been around for a while, and I’ve used it several times to get me out of tough spots. I definitely recommend that you check it out!!
