Component Location Properties

These properties refer to the package locations:

Property NameDescription
OriginalDatabasePoints the path of the current installation package. It can be a location on disk or a location in the Windows Installer cache.
ParentOriginalDatabasePoints the path of the main installation package if the current installation process was launched by a Install MSI relative or Configure MSI with specific ProductCode custom action.
SourceDirPoints the path of the MSI package folder and it shouldn't be confused with the "SOURCEDIR" property. This property is a private property so it's available only in Wizard Dialogs Stage (it cannot be used during Install Execution Stage).
TARGETDIRPoints the installation's root destination directory.
