PreinstallFolder
Full path to the pre-installation folder used by InstallMate. The pre-installation folder is a temporary folder that contains a number of installer support files that need to be available before the installation process proper starts. The folder is created automatically during all installer sessions and is also cleaned automatically at the end of the session. This makes the folder suitable to store any temporary per-session files.
Usage
You can refer to this variable as <PreinstallFolder>. Do not change its value; it has been carefully configured for cross-platform compatibility.
