Old Comp dead! Need Office on new!

Install Office on the new Dell from the Microsoft account or Workplace Discount Program associated with the purchase; the dead HP does not have to be repaired merely to uninstall Office because Microsoft permits transferring an eligible one-time Office purchase after hardware failure.^1^

1. Check whether Office is attached to your Microsoft account

1. Open the Microsoft account dashboard.
2. Sign in with the personal Microsoft account used when Office was originally purchased or installed.
3. Select Office apps, locate Office 2021, and select Install.
4. Install it, open Word, and sign in with that same account when prompted.^2^

If Office is listed, use that installation rather than entering the 63-character Installation ID again. That ID is for activation processing, not the Office product key.

Before installing, check Control Panel → Programs → Programs and Features on the Dell. If a trial or another Office edition is already installed, uninstall that copy and restart first; multiple Office installations can create activation conflicts.^3^

2. If Office Professional Plus is not listed

The correct route depends on where Office Professional Plus 2021 came from.

Purchased through an employer’s Workplace Discount Program

Professional Plus was available through the Microsoft Workplace Discount Program, formerly the Home Use Program.

1. Go to the Workplace Discount Program order-history page: https://www.microsoft.com/home-use-program/order-history?ocid=cmm3lqm9ryw
2. Enter the work email address used for the purchase.
3. Retrieve the purchase email and product key, or check whether the product was associated with a personal Microsoft account.^4^
4. After installing Professional Plus, open Word.
5. On Sign in to set up Office, select the small I don’t want to sign in or create an account link.
6. Enter the 25-character Office product key—not the 63-character Installation ID.^5^

Supplied by an employer, school, or organization

Office LTSC Professional Plus 2021 is an organizational volume-licensed edition.^6^ Contact that organization’s IT administrator for the installer and activation entitlement.

If it uses a Multiple Activation Key (MAK), replacing the computer consumes another activation from that organization’s predetermined allowance.^7^ Only the volume-license administrator can manage the key or request an activation-limit exception.

Purchased from an independent online seller

Contact the seller and request a legitimate replacement entitlement or refund. Professional Plus keys sold individually can originate from an organization’s volume-key pool; if the MAK limit has been reached or the key is blocked, the organization that owns the volume agreement must resolve it.^8^

3. If installation succeeds but activation still fails

Since telephone activation and the Installation ID portal have already failed, move directly to live support:

1. Open https://support.microsoft.com/home/contact.
2. Enter Contact Support.
3. Sign in with the personal Microsoft account used for Office.
4. Select Microsoft 365 and Office.
5. Choose the closest activation or installation category.
6. Select Chat with a support agent in your web browser.
7. Explain that the licensed computer is unusable because of power-supply failure and provide proof of purchase and the 25-character key if available.^9^

Support can assess activation only; if the key belongs to a third-party volume agreement, the seller or license-owning organization remains responsible.
