The TARGETDIR property specifies the root destination directory for the installation. TARGETDIR must be the name of one root in the Directory table. There may be only a single root destination directory. During an administrative installation this property specifies the location to copy the installation package. During a non-administrative installation this property specifies the root destination directory.
To specify the root destination directory, set the Directory column of the Directory table to the TARGETDIR property and the DefaultDir column to the SourceDir property. If the TARGETDIR property is defined, the destination directory is resolved to the property's value. If the TARGETDIR property is undefined, the ROOTDRIVE property is used to resolve the path. For more information about using the TARGETDIR property, see Using the Directory Table.
Note that the value of the TARGETDIR property is typically set at the command line or through a user interface. Setting TARGETDIR by authoring a path into the Property table is not recommended because computers differ in the set up of the local drive.
