About Project Professional 2021

Project Professional 2021 is Microsoft's desktop app for planning and tracking projects: Gantt charts, task dependencies, timelines, budgets and resource assignments. It's a one-time purchase with no subscription.

The Professional edition goes beyond Project Standard with resource management across projects, team planner views, and the ability to sync with Project Online or Project Server. Built-in reports show progress, costs and resource load at a glance.

Please note: Microsoft ends security updates for Project 2021 on October 13, 2026. Project keeps working after that date, and .mpp files stay compatible with newer versions.

Questions

Can I install Project 2021 alongside Office?

Yes, in most cases. Office and Project need the same 32-bit or 64-bit version and the same installation technology. If the installer reports a conflict, contact us before activating.

What's the difference between Project Standard and Professional?

Professional adds the team planner, cross-project resource management and connection to Project Online / Project Server. Standard is for single-user planning.

Can I open older .mpp files?

Yes. Project 2021 opens files from Project 2010 and later, and saves in the current .mpp format.

How fast is delivery?

By email, within 10 minutes – 6 hours of your payment. Check your spam folder if it hasn't arrived, or contact us with your order ID.

Is the key genuine?

Yes. It is a retail license that activates online through Microsoft's own servers.

Can I reinstall later?

Yes. Keep the key safe; it stays tied to your PC's hardware so you can reactivate after a clean install.

What if it doesn't activate?

Email [email protected] with your order ID and the error code. We replace the key or refund you within 30 days.
