The Windows Installer sets the OriginalDatabase property to the path of the installation database used to launch the installation. If the installation is launched from a command line, the value depends on whether the recache package option (the -v flag) is present in the REINSTALLMODE property.

Installation Method	OriginalDatabase Value
Any installation launched by invoking the path of the installation package (.msi file).	Path to the installation package (.msi file).
Installation launched from a command line. The installation is not launched from a package path. The recache option (-v flag) is present in the REINSTALLMODE property.	Path to the database on the source.
Installation launched from a command line. The installation is not launched from a package path. The recache option (-v flag) is not present in the REINSTALLMODE property.	Path to the cached database.

 

Remarks

During a first time installation, a custom action sequenced before the ResolveSource action can use the OriginalDatabase property to determine the location of the installation source.
