Hello , is there chance that anyone has CityEngine 2016 installer ?
Hello @MoMohamad
The latest release CityEngine 2022.1 is fully backward compatible with CityEngine 2016. You can open all your scenes created with an older version.
If your CityEngine license does not cover the latest version, please contact your local distributor to get the latest usable installer.
