- Product
- Microsoft Office Home & Student 2021
- Device & OS
- PC, Mac, Android
- Scenario
- Understanding software license limitations across different devices and determining how to access Office applications on a tablet.
- Observed behavior
- The user is unable to install or activate Office 2021 on an Android tablet because the perpetual license is restricted to a single PC or Mac.
Verify the exact version of your Microsoft Office license (such as Office 2021 versus Microsoft 365) and ensure you have the login credentials associated with your Microsoft account.
Install the Microsoft 365 Mobile App for Android
Since Office 2021 licenses are strictly for one PC or Mac, you must use the separate Microsoft 365 mobile app to view or edit documents on an Android tablet.
Office Home & Student 2021 is a perpetual (one-time purchase) license limited to exactly one Windows PC or Mac. It does not grant installation rights for Android tablets or iPads.
Unlock your Android tablet, open the Google Play Store app, and type 'Microsoft 365' into the search bar.
Locate the official Microsoft 365 (formerly Office) application and tap 'Install' to download it to your device.
Launch the app and sign in with a free Microsoft account. Note that if your tablet screen is larger than 10.1 inches, a paid Microsoft 365 subscription is required to unlock editing features.

Use WPS Office on Multiple Devices for Free
Avoid strict device limits and expensive subscription fees. WPS Office provides a fully compatible, lightweight suite for your PC, Mac, and Android tablet under a single unified account.
- 1. Download WPS Office: Get WPS Office for free from the official website or the Google Play Store on your Android tablet.
- 2. Sign In: Create a free account to seamlessly sync your files across your PC, Mac, and Android devices.
- 3. Edit Without Limits: Open, edit, and save your existing Microsoft Word, Excel, or PowerPoint files without worrying about screen size restrictions.

Frequently Asked Questions
Can I transfer my Office Home & Student 2021 license to a new computer?
Yes, Office 2021 can be transferred to another computer, but it can only be active on one PC or Mac at a time. You will need to uninstall it from the original device before activating it on the new one.
Is Microsoft Office free on Android tablets?
You can download the Microsoft 365 mobile app for free. However, if your tablet screen is 10.1 inches or larger, you will be restricted to viewing files unless you purchase a paid Microsoft 365 subscription.
Can multiple users share one Office Home & Student 2021 license?
The license is tied to the single Microsoft account used during the initial activation. Multiple people can use the same computer where it is installed, but they cannot install the software on their own personal devices using that single license.
