0patch Console is showing "NONE" in the License box

When 0patch Console is showing "NONE" in the License box, it means that:

1. 0patch Agent was properly registered
2. 0patch Service either can't connect to our server, isn't running, or isn't even installed

Probable causes for this are:

1. 0patch Agent can't connect to the server: Agent can't connect to the server. What is wrong?
2. 0patch Service is not running: 0patch Service was stopped or disabled manually or by some other product on the computer. Please make sure 0patch Service is always running and set to start automatically.
3. 0patch Service is not installed (but 0patch Agent installation seemed to have succeeded):
   1. This can be caused by another security product (e.g., HitmanPro.Alert prevents 0patch Agent from injecting into processes)
   2. This can also be caused by the DisableRollback setting set to 1; this is a non-default value that can be set by administrators for various reasons, but must currently not be in effect for 0patch Agent installation to properly succeed.
   3. 0patch only works on Intel and AMD processors; installation on an ARM machine may seem to have succeeded but 0patch Service and 0patch Driver are not installed: Which processor types does 0patch work on?
