   • Right-click and select "Run as administrator."

2. Enter Activation Commands:

   • Input the following command to navigate to the Office installation folder:

     (Replace "OfficeXX" with your specific Office version folder name.)
   • Run the command to attempt activation:

     cscript ospp.vbs /sethst:kms.your-kms-server.com
     

     (Replace "kms.your-kms-server.com" with the correct KMS server address.)

3. Activate Office:

   • Finally, use the following command:

     cscript ospp.vbs /act
     

Step 4: Verify Activation

Practical Tips

• Make sure your internet connection is stable during the activation process.
• If you encounter errors, double-check the KMS server address for accuracy.
• Keep your Office installation updated to avoid future activation issues.

Common Pitfalls
