The second hotfix to Prepar3D v4.5 (4.5.13.32097) is now available. It can be downloaded immediately from the Purchased Downloads section of the website.



Conquer the skies in the latest update to v4.5


The Prepar3D v4.5 Hotfix 2 contains numerous new features and improvements. Multiple changes have been made to improve the Virtual Reality (VR) experience including automatically hiding the VR mouse cursor when not in use, providing additional calibration options, and adding the ability to enable eye tracking by default. A new Eye Tracking Demonstration scenario is included that showcases VR eye tracking and guides a new pilot through a representative aircraft startup procedure. Distributed Interactive Simulation (DIS) ground clamping has been completely overhauled bringing enhanced realism to live, virtual, and constructive (LVC) events. Developers now have access to several new Prepar3D Development Kit (PDK) services including advanced VR interfaces that help streamline Mixed Reality (MR) integrations. Additionally, multiple bugs reported by users and developers were fixed, further improving the usability and stability of Prepar3D v4.5.

Only the Client installer is required for the majority of fixes present in Prepar3D v4.5 Hotfix 2. The Content, Scenery, and SDK installers are optional. Each fix listed below is categorized per installer. Please note, you must first have Prepar3D v4 installed to utilize any of the standalone installers (Client, Content, and Scenery).

To install the new Client, you must first uninstall your current Prepar3D v4 Client via Programs and Features in Windows Control Panel.

The Prepar3D v4.5 update may require you to reactivate your product, however if you have an internet connection or have not made any major hardware changes between installations this should not be an issue. For more information please view the Prepar3D v4 Download and Installation Directions.

The newly posted Prepar3D v4.5 (4.5.13.32097) Full Download on the Purchased Downloads page includes Hotfix 2.

Please be aware that some third party developers might have to update their add-ons to be compatible with this hotfix. Please contact the third party developers directly for any compatibility questions.
