Prepar3D v6 now supports automatic updates. This is enabled by default and checked on startup. If an >update is available a prompt will show asking to download. Additionally, the update can be installed automatically after the download is complete. Otherwise, the update file will be available in the Downloads directory on your machine to install at a later time. Installing an update file does not require any additional steps except for having Prepar3D install the update after the download is complete or manually running the update .msp file. There are no longer client/content/scenery packages that need to be uninstalled prior to updating as in previous versions. Additionally, the update file will be available on the Prepar3D Downloads page. Checking for updates can also be done on the About screen.
