How to Download an Older Office Home & Student 2021 Installer for Mac
Question details
The user needs to download a compatible, older installation file for Office Home & Student 2021 on Mac to resolve a license mismatch error.
- Product
- Microsoft Office Home & Student 2021
- Device & OS
- macOS
- Scenario
- Installing and activating Office Home & Student 2021 on a Mac running an older version of macOS.
- Observed behavior
- The installation process incorrectly reports an Office 2019 license mismatch, preventing the successful activation of the 2021 product.
Before installing a new version, verify your current macOS version by clicking the Apple menu > 'About This Mac' and ensure any previous Office 2019 installations are completely removed from your system.
Download a Compatible Build from Microsoft Update History
Identify your macOS version and download the corresponding compatible Office 2021 installer directly from Microsoft's official update repository.
Microsoft only supports the three most recent versions of macOS. If your Mac is running an older OS, you must manually download an older Office build that was released while your macOS was still actively supported.
Open a web browser and navigate to the official Microsoft page for 'Office for Mac update history' (learn.microsoft.com/en-us/officeupdates/update-history-office-for-mac).
Scroll through the release dates and select an installer package build that corresponds with the time your specific macOS version was supported.
Click the download link for the full 'Office suite' installer, ensuring it is the general release for Office 2021 and Microsoft 365, rather than a specific 2019 legacy installer.
Run the downloaded .pkg file on your Mac. When prompted during the first launch, sign in using the exact Microsoft account associated with your Office Home & Student 2021 purchase.
Download the Installer via Your Microsoft Account
Access your Microsoft account dashboard to download the specific installer tied to your 2021 license, bypassing generic installer mismatches.

Frequently Asked Questions
Why is my Mac showing an Office 2019 license mismatch for my 2021 purchase?
This typically occurs if leftover license files from a previous Office 2019 installation remain on your Mac, or if a generic installer package defaulted to an older license type. Using the Microsoft License Removal Tool before reinstalling often resolves this.
How do I know which older Office build is compatible with my macOS?
Microsoft supports the three most recent major versions of macOS at any given time. You can find a compatible build by checking the official Office for Mac update history page and choosing a version released during the period your macOS was among the top three supported systems.
Can I run Office 2021 and Office 2019 simultaneously on the same Mac?
No, Microsoft does not support running multiple perpetual-license versions of Office concurrently on a single Mac. It is highly recommended to completely uninstall the older version before installing Office Home & Student 2021.
