MediaSourceDir property

The installer sets the MediaSourceDir property to 1 when the installation uses a source located on media, such as a CD-ROM. This property is not set when the installation uses a source located at a network location. For example, the SelectionTree Control uses MediaSourceDir to determine whether the installation is being run from source or run from a network location.
