Variable that is set to a pseudo-random, probably unique session identifier each time the installer runs. It is encoded as an 8-digit hexadecimal number (with uppercase letters). It is safe to use this variable as part of a file or folder name, or a registry key or value.


You can refer to this variable as <SessionID>. Do not set this variable; it is set by all installers during each run.
