Quartus II 15.0 keeps on asking license setup

Hello,

I have a license available for Quartus Pro edition and Quartus II Development Kit Edition. I used it with Quartus Prime 19.1 without any problem. I however also need to install Quartus II 15.0 and I'm not sure if it is working or not. At each Quartus II start up, a dialog window pops up asking to set up the license even if I already set up.

I'm working with CentOS7.

I added the license to the folder ~/altera/license/. I specified the license file path accordingly in the Quartus License Setup. It seems to find information related to the license since the License setup window shows license type: full version, expiration 30-jun-2023. There is however no info regarding the NIC ID or HOST ID. And each time I restart Quartus, I keep on getting the License Setup Required dialog window, which I don't understand since the license location has been memorised by Quartus.

How can I check that the license is recognised by Quartus, and how can I stop getting that dialog box at start up?

Thanks for your help.
