It very well could be that you do indeed have the December 2015 RealTracks update.

However, I don't rely on the internal Check for Updates method since I and others have ran into problems having BIAB saying I needed this update when I know in fact that I had already updated all my patches.

I do it the old fashioned way by going straight to the PGMusic update webpage.

In this case, the RealTracks update for December 10th is here under Windows Software Updates at the top of the screen - RealTracks Update (Dec 10 2015.
