- Product
- Microsoft Office 2021
- Device & OS
- macOS
- Scenario
- Installing Microsoft Office 2021 applications on a Mac computer after purchasing or downloading the software.
- Observed behavior
- The downloaded OfficeSetup.exe file cannot be opened or executed on macOS, preventing the installation of Office 2021.
Ensure you have the Microsoft account credentials associated with your Office 2021 purchase, as you will need to sign in online to download the correct macOS installer.
Download and Install the Mac-Compatible Office Package
Bypass the Windows-only executable file by accessing your Microsoft account online and downloading the native .pkg installer designed specifically for macOS.
macOS does not natively support Windows executable (.exe) files. Attempting to open OfficeSetup.exe on a Mac will result in an error. To install Office 2021 on a Mac, you must obtain the Mac-compatible installer (.pkg file) directly from your Microsoft account.
Open a web browser on your Mac and go to www.office.com. Sign in with the Microsoft account associated with your Office 2021 purchase.
Click on your account profile icon in the top right corner and select 'My Microsoft account'. From the navigation menu, choose 'Services & subscriptions'.
Locate your Office 2021 product in the list and click the 'Install' button. The website will automatically detect that you are using a Mac and provide the correct macOS installer file.
Once the download finishes, navigate to your Downloads folder and double-click the Microsoft_Office_Installer.pkg file to launch the installation wizard.
Follow the on-screen prompts, agree to the software license agreement, and enter your Mac administrator password when prompted to complete the installation.

Frequently Asked Questions
Why can't I open OfficeSetup.exe on my Mac?
The .exe file extension stands for 'executable' and is specifically designed for Windows operating systems. macOS uses a different architecture and relies on .pkg or .app formats for software installation, meaning it cannot natively run or open .exe files.
Is my Office 2021 license valid for both Mac and PC?
This depends on the specific version of Office 2021 you purchased. Licenses like Office Home & Student 2021 can typically be installed on either one PC or one Mac. Check your Microsoft account's 'Services & subscriptions' page to verify your license compatibility.
Can I use an emulator to run the OfficeSetup.exe on Mac?
While it is technically possible to run Windows .exe files using software like Parallels Desktop, Boot Camp, or CrossOver, it is highly recommended to download the native Mac version of Office 2021 to ensure optimal performance, battery life, and integration with macOS.
Where can I find the correct Office installer for macOS?
Log in to your Microsoft account at account.microsoft.com, navigate to 'Services & subscriptions', and click 'Install' next to your Office product. Microsoft's website automatically detects your operating system and will provide the correct Mac download file.
