We can all agree that this is very exciting, the PMDG 747 has just been released for P3D v4 after a short delay! Here are the details...\n\n\tThis is a complete product and installer rebuild, thus requiring that you download the entire 1.2GB installer anew from your PMDG eCommerce account. I will include the installation instructions a bit lower down for those who need them.\n\tAs of this version, we are still awaiting a x64 compatible RAAS module from Bryan York at JetExpress\/FS2Crew. He will provide it to us when it is ready, and we will push it to you via a microupdate a bit later on. RAAS works normally in P3D v3, but it does NOT work in P3D v4. \n\tSaved flights are not currently portable between our 32bit FSX\/FSX-SE\/P3Dv3 offerings and the P3D v4 product line. We are looking to address this for a future update, so for now do not attempt to move saved flights back and forth between 32 and 64 bit product lines and you won't have any problems. \n\nOther than these warnings, you should find that the Prepar3D v4 edition of the 747-400 is a much smoother operating product thanks in part to the advancements Lockheed Martin has achieved with their simulation platform.
