Cannot Use My Product Key on a New Laptop

I went to setup.office.com, I redeemed my key and then chose 64bit. It then says Service Unavailable, try again later

Hello,

Is this the first time you are redeeming it?

What's the office product name, for example, Office Home 2024, or Pro Plus, Standard? Or Microsoft 365?

Can you go to your account https://account.live.com > Your info, is the country here the same as the country where you bought the code?

Are you currently in the same country where the code was bought?

Answer 1

If the key was accepted, the product key is already redeemed. After redemption, the key is no longer needed to install or activate Office.

Use the Microsoft account that was used during redemption:

Go to account.microsoft.com/services.
Sign in with the same Microsoft account used at redemption.
Find the Office product under Services & subscriptions.
Start the installation from there instead of returning to Office.com/setup.

If an Office app later asks for activation, sign in with that same Microsoft account rather than entering the product key again.

If the product does not appear under Services & subscriptions, make sure the correct Microsoft account is being used. A common cause is redeeming the key on one account and trying to install from another.

If the issue is specifically that the download page shows Service Unavailable after choosing 64-bit, reinstalling Office has resolved this in a similar reported case.

Hi, Jana Gordon

The “Service Unavailable” message usually points to a temporary download-page or connection problem, rather than a rejected product key.

Here are some suggestions you can try:

Open the setup page in an InPrivate or Incognito window, or use a different browser such as Edge. You can also clear the browser’s cookies and cached data before trying again.

Temporarily turn off any VPN or proxy, then try another Internet connection, such as a phone hotspot. Security filtering on a network can sometimes prevent the installer from downloading.

Check whether the new laptop already has a trial or preinstalled copy of Office. Open Settings > Apps > Installed apps, search for “Office” or “Microsoft 365,” and remove any unwanted copy. Multiple Office installations can cause setup and activation conflicts.

Run the official Microsoft 365 setup troubleshooter on the new laptop. It can detect and correct common installation problems automatically.

If the download still fails after trying another browser and network, contact Microsoft Support and provide the exact error message and proof of purchase. Do not post the product key publicly.
