I have installed the licenses of my BE, and they appear well in the SolidNetWork license manager BUT, I don't have Solidworks installed, and when I try to install via the installation manager, my license key is not valid, and no installation is possible...
Thank you very much for your contribution, I got a feedback from the hotline, apparently it would be a problem at Solidworks relating to the activation of licenses...
Indeed, when I launch the individual installation, the key is not valid, even though the licenses are activated.
I'm waiting for the call from the technician.
I'll get back to you to inform you of the next events (it can help if someone encounters the same problem)
Sometimes activation can take time. It is also absolutely necessary to be an administrator and connect directly to the server for the installation of the license server.
