Thank you for sharing the account number. I checked the details of this account and noticed that you have a floating license and not subscription license.
While installing Discovery products you get to see an option for setting license type. Since you have a floating license you need to set that option. I think the option was left as subscription due to which you are seeing the error related to subscription licensing.
Now that you have installed the products, you can still change the license type. Go to Windows start menu and type Discovery Licensing Mode Manager and open it. Then set the license type as floating, save and close it. When you launch Discovery, it will take the license or ask you to specify the server name on which the license is installed. Once that is done, the product should start.
Please let me know if you face any issues.
