PREPAR3D V4.2 NOW AVAILABLE!

Prepar3D v4.2 is available now!

Prepar3D v4.2 continues to improve on the groundbreaking Prepar3D v4 simulation platform. The new v4.2 release welcomes three new user controllable helicopters, new rendering techniques for improved virtual reality (VR) performance, countless legacy bug fixes, and even a couple new exciting experimental features to give users a feel of where the platform is heading!

This is the first release to feature new helicopter capabilities, including scenario controllable artificial intelligence (AI) and autopilot functionality. Additionally, many developer requests were addressed, and we look forward to the Prepar3D ecosystem continuing to create high-end content that pushes simulation boundaries to new limits.

For developers, we have introduced the ability to add autogen grass on airport backgrounds, added interfaces to create custom voice commands, and refined our support for complex vehicle models. Multiple Scaleform panel samples are also included better showcasing some of the newer advanced panel features that available.

All of these enhancements are available now in Prepar3D v4.2!

The Prepar3D v4.2 update is available now and can be downloaded from the Downloads page. If you currently own a valid Prepar3D v4 license there is no charge to update to Prepar3D v4.2. To purchase Prepar3D v4, please visit our online Store.

Prepar3D offers separate updates for the ClientContent, and Scenery. This will make updating faster and easier than ever before. Please be sure to read the Prepar3D v4 Download and Installation Instructions for more details on how to quickly update to the v4.2 release. Please refer to the What’s New below to see what each installer contains. Most users will only want to use the Client installer to update.

You can find a full list of What’s New below.


Release Notes

The following list of updates has been categorized based on the installer required. The Client installer is required for Prepar3D v4.2, however the ContentScenery, and SDK installers are optional. You must first have Prepar3D v4 installed to utilize the Client only installer. To install the Prepar3D v4.2 Client, you must first uninstall the previous Prepar3D v4.0/v4.1 Client through Programs and Features in Windows Control Panel.

The Prepar3D v4.2 Client update will require you to reactivate your product – with an internet connection it will be automatic.

Please view the Prepar3D v4 Download and Installation Instructions for more information.
