here is a statement from pmdg:
AEROSOFT-CD/DVD & DOWNLOAD CUSTOMERS We completed this update on Saturday morning, 10JUN17. It will take a few days for us to get all of the necessary pieces to Aerosfot so that they may update their own DVD and Download customers. We apologize for the inconvenience, but this update is simply too comprehensive to be bundled into a micro-update for instant installation. We anticipate having all of the pieces to Aerosoft for their distribution on 15JUN17.
