Official Guide: How to Install and Activate Office 2021 Pro Plus
Follow these steps to install the complete productivity suite. Ensure you remove older versions before starting.
Crucial: Uninstall Old Versions
Before installing, you MUST uninstall any previous version of Office (2016, 2019, or Microsoft 365) to avoid activation conflicts. Restart your PC after uninstalling.
Download the official installer
Use the direct link below to download the Office 2021 Professional Plus image file (IMG/ISO). This ensures you have the retail files directly from the CDN.
Run the installation
Once downloaded, double-click the file (IMG/ISO) to "mount" it (it will open like a folder). Then run the Setup file.
The installation is automated. A progress bar will appear. Wait until it says "You're all set! Office is installed now".
Open an Application
The installer does not create shortcuts on the desktop automatically. You must search for them manually.
How to find the apps
Click the Windows Start Button and type "Word" or "Excel". Open the application.
Activate your License
When you open Word/Excel for the first time, you will be asked to accept the license agreement. Then, the activation window will appear.
