Hi Nicolas Barthet
I checked your account and it seems that your license is not active on any device.
If it is telling to do entitlement license refresh, please execute license refresh command as mentioned in below post. Note that you first need to set the appropriate directory as mentioned in the initial section of this post for executing the command successfully.

If you problem persist even after doing this, please go through to this document: Discovery License Activation Troubleshooting
Also, please make sure you have installed the software while your antivirus and Windows Defender security settings were disabled
