🔍 Step 1: Remove Previous Office Versions

Before installing Microsoft Office 2021, check your system for older Office installations.

  • Go to Settings > Apps > Apps & Features
  • Look for entries like Microsoft 365 or Office Standard 2019
  • Click Uninstall to avoid software conflicts during setup

     

📦 Step 2: Prepare the Installation Files

  • Right-click and select Extract All

▶️ Step 3: Start the Office Installer

Open the extracted folder and double-click the Click To Run file.

  • Confirm any security prompts
  • This will launch the Microsoft Office installation process

 

Step 4: Let Office Install

A Microsoft window will show the installation progress.

  • Installation time may vary depending on your system and internet speed
  • Avoid shutting down your PC or running heavy applications during this step

   

Step 5: Verify Installation

Once installation is complete:

  • Open the Start menu and search for Word
  • Launch the app to confirm successful setup

       

🔐 Step 6: Begin Activation

Inside Word:

  • Click Account in the bottom-left corner
  • Select Enter Product Key to start the activation process

   

🔑 Step 7: Enter Your Office Product Key

Type in your full and correct Microsoft Office license key.

  • Make sure there are no typos to avoid activation errors

 

📄 Step 8: Accept Microsoft License Terms

Review the license agreement and click Accept and Start Word to proceed.

🌐 Step 9: Use the Activation Wizard (if needed)

If Office doesn’t activate automatically:

  • The Activation Wizard will appear
  • Choose Activate via Internet (recommended) and click Next
