Although the Performance Monitor is free we would like that you register via the Feedback form.  

Initially a 30 day Trial license will be created for you automatically.  If after 30 days you have not registered, the application will still operate but will start to remind you to register.

Once we receive your request we will respond via email with a message that will contain a license key.  Note that in order for us to provide a license key you must include your current license information in the request.

You can copy the entire body of that message and then from the License form simply press the [Paste] button and it will recognize the key for you.

Press the [Accept] button to accept and save the license.
