The Microsoft Flight Simulator 2024 Developer Alpha (Dev Alpha) is now scheduled to begin on Wednesday, Oct. 23.

We’re delaying the Dev Alpha to fix two significant crashes in the current Dev Alpha build.

Please note participation in the Dev Alpha is for official Marketplace partners only, and those eligible to participate will be notified today via email. On Wednesday when the Dev Alpha begins, eligible participants will receive another email with instructions on how to participate.

In the interim, we welcome all developers to review the Microsoft Flight Simulator 2024 SDK and its documentation (now available from the links below) and learn more about the changes to the sim.

Online Documentation
SDK Core Installer
SDK Samples Installer
SDK Wwise Installer
SDK Da62 Installer
SDK Cabri G2 Installer

Thank you for your patience!

Hello everyone,

If you have issues with 3DSMax plugin multi exporter buttons not being responsive. (Export buttons doing nothing for example),
please redownload and reinstall the SDK Core.
We had CDN cache clearing issues that could led to people downloading an older version of the installer.

Regards,
Sylvain
