1.) Install

2.) Run our keygeyn and generate a serial for 3DMark and TimeSpy DLC (if you're willing to use it)

3.) Run the program and go to "Options" tab

4.) Under "Options" uncheck "Validate result online"  ("Validate result online" option available only on
    Professional Edition license)

5.) DONE!

OPTIONAL: You might want to block the whole program with your firewall solution
          if it nags about invalid license

NOTE: If you want to change your license, delete old license using program's "Unregister"
      feature found from "Help" tab and then use our keyfilemaker again
