Office 2024: Download, Install and Activate With Your Key
By L'équipe MagicBly · Updated on August 4, 2026
In brief: after your purchase, you receive your Office 2024 key by email. Three things are left to do: download Office 2024 from the official Microsoft source, install it following the Microsoft procedure, then activate it with your key. Allow 10 to 15 minutes. Your licence is perpetual — activate it once and it stays for life on this PC.
One licence, one key, one PC. No subscription, no renewals: you activate Office 2024 once and use it for as long as you like.
Before you start: what you'll need
- Your Office 2024 activation key (in your MagicBly confirmation email).
- A compatible Windows PC with an internet connection.
- About 4 GB of free disk space.
- If an older version of Office is installed, plan to uninstall it first (see the FAQ).
Download and activate Office 2024 in 5 steps
- Get your key. Open the MagicBly email you received after your order: it contains your Office 2024 key and the official download link.
- Download Office 2024 from the official Microsoft source. Follow the link supplied with your licence (also listed on our Downloads page, which points to Microsoft). This gets you Office 2024 straight from Microsoft — an ISO image or the official installer depending on the edition.
- Install Office 2024 following the Microsoft procedure. Launch the official installer and let it run. Our Downloads page walks through the steps for the Office LTSC Professional Plus 2024 edition you bought.
- Activate with your key. When prompted to activate, enter the Office 2024 activation key (25 characters) from your email. You can also go through File → Account → Activate Product.
- Confirm the activation. The message "Product activated" appears. That's it: Office 2024 is yours, for life, on this machine.
Activation won't start?
If Word or Excel doesn't immediately prompt you to enter the key:
- go to File → Account → Activate Product;
- check your internet connection (activation contacts Microsoft's servers);
- re-enter the key without spaces, keeping the hyphens.

Good to know about your licence
- Perpetual: a one-time purchase, no subscription. You keep Office 2024 for life on the activated PC.
- One PC per licence: to set up a second machine, you need a second licence.
- Edition: the Office 2024 sold here is Office LTSC Professional Plus 2024, installed via the official Microsoft procedure (link on our Downloads page).
- Security updates included; new features, on the other hand, arrive with later versions (that's the nature of a perpetual licence, explained here).
FAQ
Where can I download the official Office 2024 ISO? Always from the official Microsoft source. The link is supplied with your licence and listed on our Downloads page. Never use a copy found elsewhere: your key is only valid with the official file.
Is my Office 2024 key valid for life? Yes. Office 2024 is a perpetual licence: once activated, it stays valid for life on that PC, with no renewals.
What should I do if the Office 2024 key won't activate? Check your connection, re-enter the key without spaces, or activate via File → Account → Activate Product. If it's still stuck, contact our support — we'll check your key and get you unblocked.
Can I install Office 2024 on several computers? An Office 2024 licence activates on a single PC. For several machines, plan on one licence per machine.
Do I need to uninstall my old Office before installing Office 2024? It's recommended, to avoid conflicts. Uninstall the old version from Settings → Apps, restart, then install Office 2024.
