Error when trying to run Windows containers: docker client must be run with elevated privileges

Hello all !
Thanks for your help !

I tried :
1. Delete C:\ProgramData\DockerDesktop if present
2. Run Docker installer as administrator (right click on exe, “Run as administrator”)
3. Installer … doesn’t work

So I launched powershell with admin privileges. Then execute the following command : “Start-Process ‘Docker Desktop Installer.exe’”

but it doesn’t work neither
