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.
SourceDirPoints the path of the MSI package folder, and it shouldn't be confused with the "SOURCEDIR" property. This property is private so it's available only in Wizard Dialogs Stage (it cannot be used during Install Execution Stage).
APPDIRPoints to the Application Folder (usually the main installation folder).
