Frequently Asked Questions
Can I use Office 2019 on multiple computers at the same time?
No, Office 2019 is a one-time purchase license that can only be installed and activated on one computer at a time. To use it on a new laptop, it must be deactivated or removed from the previous one.
Do I need my original product key to reinstall Office 2019?
If your product key is already linked to your Microsoft account, you do not need the physical key. You can reinstall the software directly from the 'Services & subscriptions' page of your Microsoft account.
What if I can't deactivate the license on my broken laptop?
If the laptop is physically damaged and cannot be turned on, you can manage your activations via your Microsoft account online. If you encounter an activation error on the new laptop, select the option for telephone activation to explain the hardware failure to the automated system or support agent.
Why is my new laptop asking me to subscribe to Microsoft 365?
Most new Windows laptops come with a pre-installed trial version of Microsoft 365. You must uninstall this trial version completely from your system settings before installing your perpetual Office 2019 license to prevent the system from prompting you for subscription payments.
