I have worked out what was stopping the track selection dialog from displaying.
The applications which hosts IL2 COD - Launcher.exe was not being run with administrative privileges on my PC, and this was preventing the dialog from displaying.
After right clicking on Launcher.exe, selecting the properties menu option, and then switching to the compatibility tab and checking the 'Run This Program as an Administrator' option, the Track Selection dialog displays and you are able to select and play tracks.
The tracks re very impressive
