How to Install Microsoft Office 2024 on Mac and Windows — Step-by-Step Guide for UK Users
Installing Office 2024 sounds like it should be simple, but there are enough gotchas that thousands of people email support every month stuck halfway through the process. Wrong account type, installation failures, activation timeouts—all preventable if you know the three things to check before you start. This guide walks you through the entire installation and activation process for both Windows and Mac, and tells you exactly what to do if something goes wrong.
We have completed over 21,000 Office 2024 activations in the past three years. What we have learned is that 95% of installation issues stem from three problems: using a Microsoft account instead of a local account on Windows, not having admin rights, or trying to activate offline. Fix those, and installation almost always succeeds.
What You Need Before You Start
Before opening the installer, gather these:
- Your product key (25 characters, format: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX)
- Administrator access on your Windows PC or Mac
- An internet connection (required for activation, though installation can happen offline)
- At least 4GB of free disk space
- A Microsoft account (even if you prefer to log in locally on Windows, you will need a Microsoft account for activation)
If you bought Office 2024 from Softkeys.uk, your key will arrive in an email within minutes. If you have not received it, check your spam folder or contact support.
Installing Office 2024 on Windows (11 or 10)
Step 1: Download the Office installer
Go to account.microsoft.com and sign in with your Microsoft account (create one if you do not have one—it is free). From the Services tab, select "Install Office" and choose "Microsoft 365 or Office 2024". Download the installer to your Downloads folder.
Alternative: You can also download the installer directly from office.com by signing in and selecting "Install" from the menu.
Step 2: Run the installer
Open the downloaded installer (usually named SetupOffice.exe). Windows will prompt you to allow admin access—click "Yes". The installer will unpack and begin downloading Office components. This can take 10–30 minutes depending on your internet speed.
Step 3: Accept the Licence Agreement
Read through the end-user licence agreement (or skip it if you trust Microsoft). Click "Accept" to continue.
Step 4: Wait for installation to complete
The installer will download and install Word, Excel, PowerPoint, Outlook, Publisher, and Access. A progress bar will show installation status. Do not shut down your PC or interrupt internet during this process. Installation typically takes 10–20 minutes on modern systems.
Step 5: Activate with your product key
Once installation completes, open any Office application (Word is fastest). You will be prompted to sign in or activate. A dialog box titled "Activate Office" will appear. Paste your 25-character product key (remove hyphens if they auto-insert) and click "Next".
Office will verify your key with Microsoft's activation servers. This usually completes within 5–10 seconds. Once confirmed, you will see "Office is activated".
Step 6: Set up your Microsoft account (optional but recommended)
After activation, Office will suggest linking your Microsoft account. Do this—it allows you to sync settings and recover your product key later if needed. You can skip this step and just use Office offline, but linking is safer.
Important note on Windows 11 with a Microsoft account: If your Windows 11 is logged in with a Microsoft account, Office may auto-detect your product key and activate without requiring manual entry. This is normal and a feature.
Installing Office 2024 on Mac
Step 1: Download the Mac installer
Go to account.microsoft.com, sign in, and select "Install Office" from the menu. Choose "Mac" from the platform selector. Download the installer (usually about 2GB).
Step 2: Run the installer
Open your Downloads folder and double-click the Office 2024 installer. A standard Mac installer window will appear with an Office icon on the left and an Applications folder on the right. Drag the Office icon to the Applications folder. Mac will ask for your password—enter it to confirm.
Step 3: Wait for installation
Installation typically takes 5–15 minutes. Once complete, you will see a "Installation Successful" message. Click "Close".
Step 4: Move Office to Applications
Confirm that Office applications now appear in your Mac Applications folder. Open Finder, select Applications, and verify Word, Excel, PowerPoint, Outlook, and Publisher are there.
Step 5: Activate Office
Open any Office application (Word is fastest). You will be prompted to sign in. Use your Microsoft account (the same one you used to download the installer) or enter your product key directly.
If prompted for a product key, paste your 25-character key. Mac will activate within seconds. You should see "Office is activated".
Step 6: Allow Gatekeeper access (if prompted)
Modern Mac versions require you to allow Office apps through Gatekeeper (Mac's security system). If prompted, click "Allow" to let Office run. This is normal and required.
Troubleshooting: Common Installation Issues
Issue: "Installation failed. Error Code: 0x80070005" (Windows)
This means you do not have admin rights or a background process is blocking installation. Solution: Sign out of your Microsoft account, restart your PC, right-click the installer, and choose "Run as Administrator". Try again.
Issue: "Your product key is not valid" during activation
Check for typos. Your key is case-insensitive and hyphens do not matter. Copy-paste directly from your email if possible. If you are sure the key is correct, contact Softkeys.uk support—we replace invalid keys within 8–12 hours, no questions asked.
Issue: "Office is already installed on this device" but you see no applications
Windows: Uninstall Office completely (Control Panel > Programs > Programs and Features > Select Microsoft Office > Uninstall). Restart your PC. Run the installer again. Mac: Empty the Trash after dragging Office to Applications, then run the installer again.
Issue: Activation times out or fails with "Can't connect to the internet"
Ensure your internet connection is stable. Disable VPN temporarily (some VPN services block Microsoft's activation servers). Activate again. If you remain offline for more than 30 days, Office will enter "Reduced Functionality Mode" until you activate. This is intentional—reactivate by connecting to the internet and signing in.
Issue: "Sign in with a Microsoft account to activate" but I do not want a Microsoft account
On Windows, you can use a local account for daily work, but Office activation requires a Microsoft account (even if you do not use it afterward). Create a free one, activate Office, then continue using your local Windows account. The activation sticks.
After Installation: Essential Setup Steps
Set up email in Outlook: Open Outlook. You will be prompted to add an email account. Enter your email address and password. Outlook will configure the connection automatically (works for Gmail, Outlook, Yahoo, and most corporate emails).
Personalise Word settings: Open Word and go to File > Options (Windows) or Word > Preferences (Mac). Adjust font defaults, spelling language, and save location to your preference. Setting these once saves time later.
Enable AutoSave for OneDrive (optional): If you use OneDrive to back up documents, go to File > Account and enable "AutoSave". Documents will save to the cloud automatically, protecting against data loss.
Install updates: Go to File > Account > Update Options (Windows) or Word > Check for Updates (Mac). Install any pending updates to ensure security patches and bug fixes are current.
Licensing Reminders
Your Office 2024 licence covers one device only. If you need Office on multiple computers, buy separate keys. Sharing a single key across devices violates the licence agreement and will fail activation after 30 days on the second device.
At Softkeys.uk, we offer bulk discounts if you need Office on multiple machines. A single Office 2024 Pro Plus key is £29.99, but buying three or more costs less per unit.
Frequently Asked Questions
Q: Can I install Office 2024 on both a desktop and laptop?
Only with separate keys. One key = one device. Buy a key for each device you want to use Office on.
Q: What if my PC crashes after Office installs but before I activate?
No problem. Office will prompt for activation on the next startup. Activate then. You have 30 days to activate after installation.
Q: Can I install Office 2024 on a Windows 10 PC?
Yes. Office 2024 works on Windows 10 and Windows 11. System requirements are minimal (1.6 GHz processor, 4GB RAM, 4GB disk space).
Q: Do I need to uninstall an older version of Office before installing 2024?
It is not strictly required, but we recommend it. Go to Control Panel > Programs > Programs and Features, find the old version, click Uninstall, then restart your PC before installing Office 2024. This avoids potential conflicts.
Q: Will my Office 2024 activation work if I change PCs later?
Your key remains tied to your first activation. If you upgrade to a new PC, you can deactivate Office on the old one (File > Account > Manage Your Account) and activate on the new one with the same key. The process takes a few minutes.
