No source file specified
The indicated installation file object has an empty source path, even though it is marked for installation.
Background information
If an installation file object is marked for installation, it must specify a source file for distribution by the installer.
Solution
Select a source file for the installation file. Alternatively, if you are using the file object only for removal of one or more files during installation, you should set its Install action attribute to a non-installation action.
