Install & activate Microsoft Project 2021

  1. Download the installer image for Microsoft Project 2021 — get it from our Project 2021 download page.
  2. Mount the image: after the download finishes, double-click the .img / .iso file. A new drive appears under This PC (this simulates inserting a DVD).
  3. Install: open the mounted drive and run setup.exe to install Project 2021.
  4. Activate: open Project, go to File → Account, choose Change Product Key, and enter the product key we sent you.

Notes

  • Microsoft Project 2021 is a one-time purchase (perpetual) — you pay once and own it.
