Thanks for your help.

After looking at the list of required items here :

I found that one of my two graphics cards was not compatible.
I disabled my NVIDIA GeForce 840M card and now it works.

Thanks again.

Thank You for your answer.

I tried this solution but it doesn’t work.

The opening is interrupted at the same step , simply , the dialog box doesn’t not appear.

Have a nice day

Jean
