Beta worked fine. Now I downloaded the whole game. When I try to start it, steam shows it’s running, aoe2de picture is showing on the desktop but no window opens and the game won’t start, no matter how long I wait. Please help.
I’m unsure if you did that, but maybe you should follow his steps and then (with everything clean): download the whole game again and try to see if the bug persist.
@Chrysalis204 - You may also want to try some of the troubleshooting steps from our support page. This article sounds similar to what you are describing: https://www.ageofempires.com/support/aoe2#aoede-exe-error
You can also try launching the game directly, instead of through the Steam client, to see if your error message changes.
