In many cases, only the “Client” portion of the update needs to be applied.But you should do your homework to best determine exactly what you need to update to take advantage of all the new bells and whistles available.
This modular setup consists of three main files with the first being the Client, the second being the Content and the third being the Scenery.
When Lockheed Martin develops, tests and deploys an updated version to us, we no longer need to completely uninstall the entire P3D application just to take advantages of the updates.
This step-by-step guide was written specifically for the Prepar3D version 4.2 to 4.3 update and written/published in late June of 2018. If you are referring to this guide anytime after version 4.3 (v4.4, v4.5 etc.) then this method should also work as well.
Unfortunately my crystal ball isn’t working for peering into the future, so who knows how the update process will work for P3D v5 (if there is such a thing).
That’s really the beauty of this modular update system.
However, I will of course update the client and also the content.While the P3D update/install files will not prompt you or even require you to reboot, it is ALWAYS in your best interest to reboot after installing software and we’re wanting a trouble-free upgrade…so just reboot! Once your Windows gaming PC has successfully restarted, launch P3D.Don’t be alarmed if P3D takes a little longer than normal to launch the first time.This way I have a better determination on just what improvements were made and how these improvements impact my setup. As I previously mentioned, I’m only planning to update the Client and the Content.So you’ll need to login to the downloads section of the Prepar3D website with your license or account credentials.To aid you in understanding all the changes included in the P3D v4.3 update, please follow this link.
