From download to activated Office
Download
Pick the file that matches your key and download it. It comes straight from Microsoft.
Mount and install
Double-click the .img file, or right-click it and choose Mount. Windows opens it as a drive: run Setup.exe and Office installs.
Activate
Open Word or Excel and enter the 25-character key from your order e-mail when asked, or under File › Account. Our activation guides show every step.
Keys for the Office you are installing
One-time purchase, no subscription. The key arrives by e-mail right after payment.
Using a Mac?
Office for Mac doesn’t come as an ISO. Office Home & Business for Mac is linked to your Microsoft account: redeem the key at setup.office.com, then install Office from your account.
- Sign in or create a free Microsoft account at setup.office.com and enter your key.
- Download Office from your Microsoft account’s Services & subscriptions page.
- Open Word and sign in with the same account. Office activates by itself.
Questions about the downloads
Stuck on an installation? Our support team helps on live chat, 24/7.
Start live chatAre these downloads safe and legal?
Yes. The links point to Microsoft’s own download servers (officecdn.microsoft.com), so you get the original, unmodified installer. Downloading and installing is free; you need a valid product key to activate Office.
Which file do I need?
The one that matches your key: the same version (2024, 2021, 2019 or 2016) and the same edition (Professional Plus, Home & Business, Home & Student, Project or Visio).
How do I open an .img file?
On Windows 10 and 11, double-click it, or right-click it and choose Mount. It opens like a DVD drive; run Setup.exe from there.
The download is slow or stops. What can I do?
The files are 4.3 to 5.5 GB. A wired connection helps, and most browsers and download managers can resume a stopped download.
Can I install Office in another language?
These files are in English (US). After installing, you can add a language in any Office app under File › Options › Language.
Is there an ISO for Office on a Mac?
No. Office for Mac installs from your Microsoft account after you redeem your key at setup.office.com. See Using a Mac? above.
