Hi Terri, you will need to contact Microsoft Support to 'delink/deactivate the installation on the crashed hard drive. Whether or not you can use the Product Key to reinstall the Office 2019, will depend on how the counterfeiter adapted the software. Had your office been a legal version it would be available at Services & Subscriptions of the Microsoft Account used with the Product Key to redeem your Office at: https://account.microsoft.com/services
You could try redeeming Office 2019 using the Product Key and Microsoft Account here: http://www.office.com/setup
