InstallMate sets this variable to the serial number of the builder's registration code. See Build-time variables for details about when InstallMate assigns values to build-time variables.
Note: This variable is primarily intended for use in build actions. Therefore, and because it might contain potentially sensitive information about your development system, it is not saved in the installer's database by default. If you want to use this variable as part of your installer, you must check its Include in installer box in the Symbolic Variable attributes pane. If you fail to do so, InstallMate will issue a BLD:W0103 diagnostic when you build the project.
You can refer to it as <BuildSerial>. Do not set this variable directly; it is set automatically each time InstallMate builds a project.
