How to move your Office licence to a new computer
Bought a new PC or Mac? Your one-time Office licence can move with you — one device at a time. Here is how to transfer it cleanly.
Before you start
- The Microsoft account you redeemed the key with
- Access to the old computer (helpful, not essential)
- An internet connection
-
01
Deactivate on the old machine
On the old computer open Word → File → Account → Sign out, then uninstall Office from Settings → Apps (Windows) or drag the apps to the Bin (Mac). This frees the licence.
-
02
Open your Microsoft account
Go to account.microsoft.com → Services & subscriptions. Your Office 2024 or 2019 edition is listed with an Install button.
-
03
Install on the new computer
Click Install, run the downloaded setup file and wait for it to finish.
-
04
Activate
Open any Office app and sign in with the same Microsoft account. Activation is instant.
-
05
Tidy the device list
Under Services & subscriptions → Devices you can see where the licence is active. Remove old machines you no longer own.
If something goes wrong
Common snags.
The old computer died — I cannot deactivate it
Skip step one. Install on the new machine and sign in; if activation says the licence is in use, remove the old device from the Devices list online.
Can I run it on two machines at once?
No. A perpetual licence is one device at a time. Need a second? Ask us about volume pricing.
I switched from Windows to Mac (or back)
Office 2024 licences are platform-specific. Contact us and we will advise on the right edition.
