Stop wrestling with disconnected task lists and chaotic spreadsheets. Microsoft Project 2021 Professional MAK is the definitive, one-time purchase project management desktop application engineered for professionals who need to plan, execute, and deliver complex initiatives with absolute precision.

Whether you are a seasoned project manager, a portfolio planner, or a business analyst operating within a corporate environment, this MAK (Multiple Activation Key) volume license edition unlocks the complete scheduling engine, resource management tools, and advanced reporting capabilities that Microsoft Project is famous for—without any dependency on a Microsoft 365 subscription.

The key advantage is absolute ownership: pay once, use forever, with the confidence of a genuine, verified volume license designed for professional environments that demand stability and long-term cost control.

What's included with your purchase
When you complete your order, you receive a complete, ready-to-use licensing package delivered instantly via email. The core of your purchase is a genuine Microsoft Project 2021 Professional MAK (Multiple Activation Key). This is a volume license key designed for businesses and professionals, allowing a single activation on one Windows PC. Unlike a subscription that expires after a month or a year, this license is permanent and does not expire. You are buying a lifetime right to use this version of the software.
Your package includes the official MAK license key, a direct download link to the official Microsoft installation media, a VAT invoice suitable for business accounting, and a clear, step-by-step activation guide. The activation process is straightforward: download the software from the official Microsoft source, run the installer, and when prompted, enter the MAK key. The system will activate online or via a one-time phone activation, binding the license permanently to your device’s hardware. This edition is fully compatible with Windows 10 and Windows 11, and you can install it alongside other Microsoft Office 2021 applications without conflict.
Choosing the right edition
Selecting the correct edition of Microsoft Project is critical to ensuring you have the right tools without overspending. The 2021 Professional edition sits at the sweet spot for most business users, but understanding the landscape helps you make an informed choice.
Project Standard 2021 vs. Professional 2021: The Standard edition is a solid, entry-level desktop scheduler. It handles task management, basic resources, and Gantt charts. However, it lacks the collaborative and enterprise features that define the Professional edition. If you need to synchronise with Project Online or Project Server, use resource engagement views, submit timesheets, or manage a portfolio of projects, Professional is mandatory. Standard is for an isolated planner; Professional is for a connected project manager.
Project Professional 2021 vs. Project Plan 3/5 (Subscription): This is the most important distinction. Project Professional 2021 is a one-time purchase for a single device. You own it. Project Plan 3 and Plan 5 are Microsoft 365 subscriptions that include the desktop client but are billed per user per month. They offer cloud-based co-authoring and advanced analytics that the on-premises 2021 version does not. Choose the 2021 Professional MAK license if you want long-term cost certainty, do not require real-time co-authoring, and prefer a perpetual license over an operational expense.
Who needs the Professional edition? You need this edition if you are a full-time project manager, a resource manager, a PMO analyst, or anyone who must consolidate multiple project files into a master plan, manage shared resource pools, or report consolidated project status to senior leadership.
System requirements / compatibility
To ensure optimal performance, your device must meet the following minimum specifications. Microsoft Project 2021 Professional is a 64-bit application designed for modern Windows environments.
Operating System: Windows 10 (version 1809 or later) or Windows 11. It is not compatible with Windows 7, Windows 8.1, macOS, or ChromeOS.
Processor: 1.6 GHz or faster, dual-core. For professional-grade schedules with thousands of tasks, a faster multi-core processor is recommended.
Memory (RAM): 4 GB minimum for 64-bit systems. For large, complex project files with nested sub-projects, 8 GB or more is strongly advised.
Hard Disk Space: 4 GB of available disk space.
Display: 1280 x 768 screen resolution.
Graphics: DirectX 10 compatible graphics card for hardware acceleration.
Additional Requirements: Internet access is required for product activation and to access online help and templates. A Microsoft account is required for the initial activation process. Please note that these are the minimum requirements published by Microsoft; for the best experience, always verify the latest specifications on the official Microsoft website before purchasing.
Installation and activation
Your license journey is designed to be secure and immediate. After your payment is processed through our encrypted checkout, you will receive a confirmation email containing your unique MAK product key and a direct link to download the official Microsoft installation media. Delivery is typically instantaneous, with the average customer receiving their license in under 60 seconds.
To activate, download the installer from the link provided and run it as an administrator. During the installation wizard, you will be prompted to enter the 25-character product key. Enter the MAK key exactly as provided. Once installation completes, launch Microsoft Project. It will attempt to activate online automatically. If online activation fails due to a firewall or proxy, the software will present a telephone activation option where you can obtain a confirmation ID. The license binds to your device’s motherboard, meaning you can reinstall the software on the same device as many times as needed without issue. If you decommission the old PC, the license is not designed to be transferred to a new device, which is standard for this MAK volume license type.

FAQ — frequently asked questions
Is Microsoft Project 2021 Professional a subscription or a one-time purchase?
This is a one-time, perpetual purchase. You pay a single upfront cost and receive a license that does not expire. This is fundamentally different from Microsoft Project Plan 3 or Plan 5, which are recurring monthly or annual subscriptions.
What is a MAK license and how does it differ from a Retail key?
A MAK (Multiple Activation Key) is a volume license designed for businesses. Unlike a Retail key, which is packaged for consumers and can sometimes be transferred, a MAK key is typically used for a single activation and is bound to the device’s hardware. It is a genuine, permanent license, but it operates under volume licensing terms rather than retail packaging terms.
How fast will I receive my license key after payment?
Our delivery is fully automated and instantaneous. On average, customers receive their official download link and MAK product key via email in under 60 seconds. Please check your spam folder if it does not appear in your primary inbox immediately.
Is this a genuine and legal Microsoft license?
Absolutely. Lizensa supplies exclusively 100% genuine, verified licenses sourced from authorised European distribution. You will receive a legitimate key that passes Microsoft’s online activation and validation checks, and you are provided with a full VAT invoice for your records.
What should I do if I encounter an error during activation?
First, ensure you are entering the key exactly as provided, without any extra spaces. If an online activation error occurs, use the built-in telephone activation wizard in Windows to get a confirmation ID. If you still face issues, our free multilingual support team is ready to assist you via email.
Can I reinstall the software or transfer the license to a new computer?
You can reinstall the software unlimited times on the same device. However, this MAK volume license is generally non-transferable. It binds to the motherboard of the first PC it is activated on, so it cannot be moved to a new computer if the original device is retired.
Does this license work in my country within the EU?
Yes. This license is valid for activation and use across all 27 EU member states. There are no regional restrictions within the European Union, and the software interface supports all major international languages.
What payment methods does Lizensa accept?
We accept a wide range of secure payment methods through Stripe, including credit and debit cards (Visa, Mastercard, American Express), SEPA bank transfers, iDEAL, BLIK, and Google Pay. Your financial data is always encrypted and never stored on our servers.
Do you provide a VAT invoice for my purchase?
Yes, a detailed VAT invoice is automatically generated and included with your delivery email. For B2B customers with a valid EU VAT ID, the reverse charge mechanism is applied, resulting in a net invoice without VAT.
What is your refund policy?
We offer a 14-day right of withdrawal in compliance with EU consumer protection laws. If you have not activated or downloaded the software, you can request a full refund. Due to the nature of digital license keys, refunds for keys that have been viewed or activated are restricted to prevent fraud.
Can I use this with Microsoft Teams or SharePoint?
Yes. While Microsoft Project 2021 Professional is a desktop application, you can save your project files (.mpp) to SharePoint document libraries for centralised storage. However, real-time co-authoring is a cloud feature exclusive to the subscription-based Project Plan 3 and Plan 5.
Does this version include the new Project for the web interface?
No. Project 2021 Professional is the classic, full-featured desktop client. "Project for the web" is a separate, lightweight browser-based interface available only through specific Microsoft 365 subscriptions. This desktop client provides the most powerful scheduling engine available.
