My Dell xps13 hard disc has died, so I want to load its copy of Office 21 to a reconditionsed Dell Lattitude 7400.

How do I go about this?

Hi, I'm John! I will help you with this.

If the old PC is no longer available or activation does not work:

Install Office from https://account.microsoft.com/services on the new PC using the same Microsoft account.

If activation fails, contact Microsoft Support and explain that the previous PC was returned or is no longer usable. They can help reset the activation:

  • Here is the link: https://support.microsoft.com/home/contact
  • Type this keyword and press Enter: Contact Support.
  • At the bottom, click "Sign in to contact support" and sign in with your Personal Microsoft account (Not work or school account), or click "Contact Support" if you're already signed in.
  • In Product and services, select "Microsoft 365 and Office".
  • In Category, select "Manage my subscription".
  • Click "Chat with a support agent in your web browser".

If you ever find yourself stuck in a loop, please use the keywords "Contact Support" or "Live Chat" (without the quotes) and click "Contact Support" at the bottom.

I really hope this information is helpful! Let me know if you have any further questions or concerns.

Regards,

John J.D.
