The file system path or URL to the Flex application that you want to add to the list.
Note: The Flex Runtime Loader fails to open the application if you use certain Unicode fullwidth characters in the path. For example, make sure not to include English fullwidth letters or Japanese fullwidth number characters.
If you are testing applications developed using Flex SDK version 4.12.x, use the AddApplicationInIE32WithRuntimeLoaderEx Method instead.
By default, both methods use the 4.9.1 Runtime Loader.
