If you need reliable project-management software on your Windows 10 or 11 PC, Microsoft Project Professional 2021 (Project Pro 2021) delivers a robust solution when properly downloaded, installed, and activated. This guide walks you step by step through the full process — from getting the install files to entering your product key — so you can get started quickly and smoothly.
What You Need Before Installing Project Professional 2021
Before beginning the installation, make sure you have:
- A stable broadband connection — you need it to download the installer and complete online activation. ecokeys.co.uk+1
- A genuine 25-character product key (license) for Project Professional 2021. ecokeys.co.uk+1
- A PC running Windows 10 or Windows 11, with enough free disk space and sufficient hardware specs. ecokeys.co.uk+1
If you fulfill those prerequisites, you’re ready to proceed.
Step 1: Download the Installer
- Use the official download link:
https://officecdn.microsoft.com/db/492350f6-3a01-4f97-b9c0-c7c6ddf67d60/media/en-us/ProjectPro2021Retail.img ecokeys.co.uk+1 - If your browser warns the file could “harm your PC,” proceed anyway — this is a legitimate Microsoft-hosted disk image. Some browsers block .img files; switching to a browser like Firefox can help. ecokeys.co.uk
- The download should land in your “Downloads” folder (or wherever you save downloaded files). ecokeys.co.uk+1
Step 2: Mount and Install Project Pro 2021
- Find the file named ProjectPro2021Retail.img in your download folder and double-click it. Windows will treat it like a virtual disc and mount it. ecokeys.co.uk+1
- Inside the mounted image, locate and double-click setup.exe (or “Setup”). This will launch the installer. ecokeys.co.uk+1
- Follow the on-screen prompts — accept any license agreements and confirm prompts like User Account Control. The installation typically takes 10–30 minutes, depending on your PC speed and internet connection. ecokeys.co.uk+1
- Once the installer finishes and shows the “Completed” screen, click “Close” — do not restart yet. Then restart your PC to ensure all components initialize properly. ecokeys.co.uk+1
Step 3: Launch and Activate Project Pro 2021
- After reboot, open the Start menu and search for “Project” — click to launch the application. ecokeys.co.uk+1
- On first launch, you should see an activation prompt. Paste in your 25-digit product key into the “Enter an Office product key” field. ecokeys.co.uk+1
- Choose “Activate online” if prompted — this connects to Microsoft’s servers to validate the key and activate your software. ecokeys.co.uk+1
- Once activation completes, Project Professional 2021 becomes fully functional and ready for use. ecokeys.co.uk+1
