Project 2021 Professional Key

What you get

After payment you receive a 25-character Project Professional 2021 product key by email, instantly in most cases (a system delay can occasionally add 5–10 minutes). The email includes the link to Microsoft’s website and our step-by-step installation guide, and the key is also saved under My Account → Keys.

What is Project Professional 2021?

Project is Microsoft’s desktop app for planning and tracking projects: tasks and dependencies, Gantt charts, timelines, resources, costs and ready-made reports. Professional is the full edition. On top of everything in Project Standard, it adds:

• Team Planner, to see and schedule who works on what
• Inactive tasks, to test what-if scenarios without deleting tasks
• Connection to Project Online and Project Server for team collaboration and resource management

License and activation

This is a retail Project Professional 2021 key for one PC. You redeem it on Microsoft’s official website, setup.office.com, with your Microsoft account, then download Project from Microsoft and activate it online. Because the key is redeemed to your Microsoft account, the download stays available in your account.

Is it genuine? Why is it cheaper than Microsoft’s price?

Yes. It’s a genuine Microsoft key that you redeem and activate on Microsoft’s own website. We buy unused keys from companies that purchase Microsoft licenses in large batches and have more than they need, and we pass that lower price on to you.

The key you receive is exactly the one described here: a retail Project Professional 2021 key for one PC, activated online.

How to install and activate Project 2021

1. Uninstall older Project versions from the PC.
2. Go to setup.office.com, select Get Started and sign in with your Microsoft account (or create one for free).
3. Enter your product key, choose your language and select Redeem.
4. Download Project from your account and run the installer. Choose the same 32-bit or 64-bit version as the Office already on your PC.
5. Open Project and sign in with the same Microsoft account if asked. If the activation wizard appears, choose “I want to activate the software over the Internet”.

If activation fails

• “This product key can’t be used”: check that you typed the key exactly as in the email and that you’re redeeming it for Project Professional 2021.
• Setup stops because of Office: Project has to match the 32-bit or 64-bit version of your Office installation. Install the matching version.
• Anything else: contact us within 15 days of your order, on live chat or at support@cheapkeys.io. We’ll fix it or replace the key, and if no working solution is possible, you get a refund under our refund policy.
