Location Repository
Each Component of the Version can have its own location in file-system hierarchy of the end-user's system. To determine where exactly the particular Component should be located we shall use a special table called the Location Repository. This table is the integral part of the product description (i.e. associated with each product), and should be filled by the user.
Each item of the Location Repository is a named record. The parameters of each record define the way to determine the full path to the each component location on the end-user's machine.
The "Location" property of a Component defines which record from the Location Repository is used to detect this Component location.
Currently the following types of records are available:
1. Registry
The full path to component's files location is taken from one of the Registry keys.
