How to install & activate Office 2021 Professional Plus

Install and activate Office 2021 Professional Plus using Microsoft’s official Office Deployment Tool (about 10 minutes):

1. Uninstall any other Office / Microsoft 365 version first: Control Panel → Programs → Uninstall a program. Mixed versions are the #1 cause of activation errors.
2. Download the Office Deployment Tool from the Download tab, run it and extract it to a folder, e.g. C:\ODT.
3. In that folder create a file configuration.xml with this content (put your key in place of YOUR-PRODUCT-KEY):
   <Configuration><Add OfficeClientEdition="64" Channel="PerpetualVL2021"><Product ID="ProPlus2021Volume" PIDKEY="YOUR-PRODUCT-KEY"><Language ID="en-us" /></Product></Add><Display Level="Full" AcceptEULA="TRUE" /></Configuration>
4. Open Command Prompt as Administrator, run cd C:\ODT and then setup.exe /configure configuration.xml. Office downloads and installs.
5. Open Word → File → Account. If it does not say Product Activated, click Change Product Key, paste your key and click Activate.
6. Alternative (Administrator Command Prompt): cscript "C:\Program Files\Microsoft Office\Office16\OSPP.VBS" /inpkey:YOUR-PRODUCT-KEY then cscript "C:\Program Files\Microsoft Office\Office16\OSPP.VBS" /act.

💡 If setup says the key is not valid for this product, change the Product ID in the XML from ProPlus2021Volume to ProPlus2021Retail and run setup again.

💡 Microsoft support for Office 2021 ends on 13 October 2026. For longer support choose Office 2024.
