Easy. Run the installers for everything onto your System Drive.

Copy the RT and Drums folders over to your external.

Open BIAB. From the Window menu, scroll down to Real Tracks Settings and Real Drums settings, select the external.

Now empty the RT and Drums folders on your system drive — do nor remove the folders. This way, if a future update or Pack installs something into those folders, you can copy those files to your external.
