Steps to Complete:
1. Navigate to the following directory: C:\Program Files (x86)\ComponentOne\C1StartMenu
2. Run the C1LicenseActivation tool. If this tool and directory do not exist, you can download the tool here: http://cdn.componentone.com/files/LicenseActivation/C1LicenseActivation_2.0.20173.93.zip
3. Next to the Serial Number field, there should be a "?" button. Click the button to display any keys currently active on your machine. If no keys are displayed, that means there is no key active on the machine.
