About Media Location Manager
Media Location Manager lets you view and modify Windows Installer Package(.msi) source locations for all products on your machine that are installed with Windows Installer. A graphical and command line version of Media Location Manager is provided with installation.
The Media Location Manager dialog box consists of two components:
Installed Products area—Lists all products that have been installed with Windows Installer, along with their versions and product codes.
Source Information area—Lists all locations where Windows Installer can potentially find the .msi file for a particular product, along with their source types and indexes.
Whenever a product requires installation information (for example, in cases where a product feature is installed on-demand), Windows Installer automatically searches all source locations associated with the product, for the required .msi file. If there are no source locations associated with the product, then you are prompted to provided a valid one the next time Windows Installer attempts to search for the .msi file. In effect, Media Location Manager lets you manage source locations to improve source resiliency for all products listed in the Media Location Manager dialog box.
