Fail to check dependencies

Hi, 

As I try to install Minecraft dungeons, it fails right at the end.

Message displayed is :

• Fail to check dependencies in game (approximate translation from french
• Unable to instal the game

I can't find the folder where it is supposed to be installed.

When I try to launch the game, is displays an error message :

Couldn't start :

"C:\...\...\AppData\Local\Mojang\Products\Dungeons\Dungeons\Dungeons\Binaries\Win64\Dungeons-Win64-Shipping.exe"

Dungeons -launcherDir C:\...\...\AppData\Roaming\.minecraft-activeUser 2533275005206721

CreateProcess() returned 2.

 

What's happening... ?

thanks for your help
