Matt Davies has clarified on the rumour we suggested below. We would like to apologize as it appears we made a mistake on some of the information given to us. If you have any further comments, please do get in touch. Sorry again! (Cal) Thanks to everyone who sent us the clarification and Matt for correcting us.

Matt has made it very clear that it doesn’t require a full install and confirms that you’ll have to update the individual components (client, content and scenery). He is creating a video to help make the process as easy as possible to update, which when released, we’ll share as well to support you with the process.


Update – We’ve clarified a few points.

Tomorrow, according to Lockheed Martin, is the day they will release the anticipated update to version 4 of the Prepar3D simulator. Version 4.1 promises to be a relatively big update as they have listened to developer feedback to improve the sim even further. Whilst the official change log hasn’t been released, Lockheed Martin did identify that changes to the way dynamic lighting is used has been looked at and will include the first steps to bringing back virtual cockpit rain effects. Of course, this update will be free of charge.

So what is this article? Well we just wanted to send a friendly reminder that whilst a new update is really exciting, we need to remember that key products may or may not work out of the box. Add-ons such as Active Sky 16, FSUIPC, and Orbx’s Libraries and ObjectFlow usually require an update before they work in the sim. We’ve been informed that FSUIPC (thanks David) has already been updated to work with the new sim and we’re in touch with some other developers to see if they’re ready. If they aren’t, they’re usually pretty speedy updating their installers, but just remember to have some patient as they work on it.

Of course, we know that 29Palms are eagerly awaiting this update as it means they can release their Skiathos scenery and FSLabs are also waiting for 4.1 to be released. Once it’s out, we imagine both products won’t be far behind.

– Removed Rumour –

Of course, we’ll give you the full low-down tomorrow at 3PM EST (10th October 2017 @ 1900z) when it’s due to be released.

    1. Or maybe just a summary for those who still don’t know much about the coming update. Just a thought…

    2. Just a recap / summary and setting expectations for people excited to update when it’s released.

  1. I hope it’s not a full reinstall of everything. A past article said it may be client or content only.🤞

    1. Yeah, we assumed it would be as per past releases. Multiple people have told us it’s a full install. We’ll see tomorrow 🙂

  2. I asked a week ago if it’s a stand alone or update.
    If it will be a complete install,then count me out.

    1. You’ll probably update at some point as add-on products going forward will probably be compatible with the latest version only.

  3. Click bait? LOL. Sounds like a bunch of whiners in need of some pablum with the pompous comments. Just click download when you hit the sack and it will be waiting for you the next day. I appreciate the notification as well, as I wasn’t aware there was an update until I checked in.

    Thank you for your efforts, Calum, much appreciated!
