# Can I Use This Office Key on Mac or PC?

Before installing your software, it’s important to know whether your license is compatible with Windows, macOS, or both.

### 💻 Windows vs. Mac compatibility

**✅ Microsoft Office for Windows**  
Includes: Office 2019, 2021, 2024 (Standard & Pro Plus), and Microsoft 365  
Compatible with: Windows 10 and Windows 11  
Not compatible with: macOS

If you’re using a Windows PC, you should install the Windows version.

**🍏 Microsoft Office for Mac**  
Mac editions are sold separately (for example, Office 2021 for Mac).  
Compatible with: macOS versions such as Monterey, Ventura, Sonoma, and newer  
Not compatible with: Windows

If you’re using a Mac, make sure your purchase clearly states it’s for Mac.

**⚠ Important  
A Windows-only Office installer will not run on macOS, and a Mac-only installer will not run on Windows.**

**If you accidentally purchased the wrong platform version, contact us. If the key hasn’t been used, we’ll help you switch to the correct option.**
