Project Professional 2024 activates via setup.microsoft.com — the same portal used by Office Home & Business, not the Volume Licensing Service Centre used by Office Pro Plus. Get that distinction wrong at the start and the process stalls immediately. This is the complete activation walkthrough for Windows, what to do if anything goes wrong, and how to confirm it has completed properly.
Which activation method applies to you
Microsoft sells Project through several different channels, and each activates differently. Using the wrong method wastes time and triggers errors that look like something is wrong with the key when nothing is.
| Product | Activation route | Microsoft account needed? |
|---|---|---|
| Project Professional 2024 — retail perpetual key | setup.microsoft.com | Yes — free to create |
| Project Plan 3 / Plan 5 (subscription) | Microsoft 365 admin portal — licence assigned to user account | Yes — managed by admin |
| Project Server Subscription Edition | Enterprise on-premises deployment — no product key involved | AD/Entra account |
If you purchased a retail key from Software Supplies, you are in the first row. The steps below cover that route in full.
If you also have Office Professional Plus 2024, that product activates via the Volume Licensing Service Centre or Key Management Service — not setup.microsoft.com. The two activation methods are completely separate. Activating Project through setup.microsoft.com does not affect your Office Pro Plus installation.
What you need before you start
Two things are required and everything else is handled during the process itself.
- Your 25-character product key — delivered to your inbox immediately after purchase, formatted as XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
- A Microsoft account — free to create at account.microsoft.com if you don’t already have one. The Project licence will be permanently tied to this account, so use one you intend to keep
- An internet connection — needed for the key redemption and initial activation handshake. Once activated, Project works fully offline
- A Windows PC — Project Professional 2024 is Windows only. There is no Mac version
Project installs alongside Office without conflict. The two products share the same Click-to-Run update mechanism but are entirely separate applications. Do not attempt to add Project through the Office installer — it has its own dedicated setup file downloaded from setup.microsoft.com.
Step-by-step: activating Project Professional 2024
Work through these steps in order. The entire process — from key redemption to confirmed activation — takes around 15–25 minutes, depending on your connection speed.
-
Go to setup.microsoft.comOpen a browser and navigate to setup.microsoft.com. This is Microsoft’s official key redemption and download portal for retail perpetual licences including Project.
-
Sign in or create a Microsoft accountYou’ll be prompted to sign in. If you don’t have a Microsoft account, create a free one — it takes under two minutes. Your Project licence is permanently tied to this account once redeemed, so use an account you intend to keep.
-
Enter your 25-character product keyType or paste the key exactly as it appears in your order email. Dashes are inserted automatically — enter the 25 alphanumeric characters without spaces or punctuation.Key format: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
-
Confirm country and languageSelect United Kingdom and your preferred language, then click Next. The licence is now permanently attached to your Microsoft account — even if you close the browser at this point, the key has been redeemed.
-
Download the Project installerClick Install Project. Microsoft’s portal provides the correct installer for Project Professional 2024. Run the downloaded file — the actual application downloads during setup, not from the initial file.Typical download: 1.5–2 GB depending on installed components
-
Run the installer and waitFollow the on-screen prompts. Installation takes 10–20 minutes on a typical broadband connection. Project will appear in your Start menu once complete. You don’t need to do anything during the installation itself.
-
Open Project and sign inLaunch Microsoft Project from the Start menu. On first open, you’ll see a sign-in prompt or an activation screen. Sign in with the same Microsoft account used in step 2. Project checks the licence against your account and activates automatically.
-
Confirm activationGo to File → Account. Under Product Information, you should see the product name alongside Product Activated in green. You’re done.
Activating on a machine where Project is already installed
Some users already have Project installed — from a trial, a previous employer’s licence, or an earlier version. The process is slightly different: redeem the key first, then sign in from within the application.
-
Redeem the key at setup.microsoft.comDo this first, before opening Project. Go to setup.microsoft.com, sign in to your Microsoft account, and enter the key. Once the portal confirms redemption, the licence is attached to your account.
-
Open ProjectIf you see a sign-in prompt or an “Unlicensed Product” banner at the top of the window, that’s expected — it means Project has detected no active licence for the current user.
-
Sign in with the account the key was redeemed againstGo to File → Account → Sign In and enter the credentials for the Microsoft account you used at setup.microsoft.com. Project contacts Microsoft’s licensing servers and activates automatically.
-
Confirm activationFile → Account → Product Information should now show Product Activated. If it doesn’t, sign out of the account within Project and sign back in — this forces a fresh licence check.
How to confirm activation is complete
Once activation has gone through, the confirmation is unambiguous. Here’s what each state looks like so there’s no guessing.
If you’re seeing the yellow unlicensed banner after signing in, sign out of your Microsoft account within Project (File → Account → Sign Out), close all Project windows completely, reopen, and sign back in. This forces a fresh licence check and resolves the majority of post-activation display issues.
Troubleshooting common activation errors
Activation problems with retail keys are uncommon but not rare. Every error below has a specific cause and a specific fix.
Usually means a subscription licence code is being entered into the retail key flow, or the wrong version of Project is installed. Confirm your key is a retail perpetual product key — it will be a 25-character alphanumeric code in the XXXXX-XXXXX format. Subscription codes look different and are assigned through the Microsoft 365 admin portal, not setup.microsoft.com.
Also confirm you have downloaded Project Professional 2024 specifically from setup.microsoft.com — not Project Standard, and not an older version. If everything looks correct and the error persists, our support team is on hand 9am–6pm, seven days a week at [email protected].
This code usually appears after multiple failed activation attempts in quick succession — Microsoft’s activation servers temporarily block the key to prevent abuse. It does not mean the key is invalid. Wait 30 minutes, then attempt activation again from scratch. If the error persists after waiting, our support team is available 9am–6pm, seven days a week at [email protected] and can resolve this quickly.
The licence is already active on another machine. Project Professional 2024 covers one PC at a time. To move it, sign in to account.microsoft.com, go to Services & Subscriptions, find Microsoft Project, click Manage, and deactivate the old device. Then activate on the new machine by signing into Project with the same Microsoft account.
Trial mode means the key has not yet been redeemed. Project launches in a 30-day trial when no licence is attached to the signed-in account. Go to setup.microsoft.com, sign in, and enter your key. Once the portal confirms redemption, open Project and sign in with the same account — trial mode will clear immediately.
Project needs a brief internet connection to complete the initial licence handshake with Microsoft’s servers. Check your connection is active, temporarily disable any VPN or proxy software, and retry. This error is almost always transient — once the handshake completes, Project works fully offline with no recurring check-ins required.
Transferring your licence to a new PC
Retail perpetual licences are transferable. If you replace your machine, the licence moves with you.
-
Deactivate on the old machineSign in to account.microsoft.com. Go to Services & Subscriptions, find Microsoft Project Professional 2024, click Manage, and select Install on a new device or deactivate the current one.
-
Install Project on the new PCSign in to setup.microsoft.com with the same Microsoft account. The portal will show your redeemed Project licence. Click Install to download the installer for the new machine.
-
Sign in and activateOpen Project on the new machine and sign in with the same Microsoft account. Activation is recognised automatically — no key re-entry required.
If the old machine is no longer accessible — lost, stolen, or failed — Microsoft allows a self-service deactivation via the account portal. If you encounter any difficulty, Software Supplies support can assist: [email protected].
Common questions
Yes — a Microsoft account is required to redeem the product key at setup.microsoft.com and to complete the initial activation. The account is free to create. Once activated, Project runs fully offline with no requirement to stay signed in. The licence is permanently attached to the Microsoft account used during redemption, which is also what enables licence transfers to new hardware.
Yes. Project and Office install and run alongside each other without conflict. Both use Microsoft’s Click-to-Run delivery mechanism and share the same update channel, but they are separate applications with separate licences. Installing Project does not affect your Office installation, and vice versa. The one thing to avoid is trying to add Project through the Office installer — use setup.microsoft.com to get the Project-specific setup file.
The initial installer file from setup.microsoft.com is small — under 5 MB. The actual application downloads during installation and totals around 1.5–2 GB. On a standard UK broadband connection (50–100 Mbps), the full installation including download takes 10–20 minutes. The process is hands-off once started — you don’t need to make any choices after the initial prompts.
The initial activation requires an internet connection — Microsoft’s servers need to verify the key and attach the licence to your account. Once that handshake is complete, Project works fully offline with no further check-ins. There is no periodic re-activation requirement. This makes it suitable for use on site, while travelling, or in environments with restricted network access.
Different routes entirely. Project Professional 2024 is a retail product activated through setup.microsoft.com using a Microsoft account — the same process as Office Home & Business. Office Professional Plus 2024 is a volume licence product that activates through Microsoft’s Key Management Service (KMS) or the Volume Licensing Service Centre — no Microsoft account required. The two methods are completely separate and do not interfere with each other if both products are installed on the same machine.
Yes. Retail perpetual licences are transferable. Sign in to account.microsoft.com, go to Services & Subscriptions, find your Project licence, and deactivate the old device. Then install Project on the new machine and sign in with the same Microsoft account — activation is recognised automatically. The licence can only be active on one machine at a time, but there is no limit on how many times you can transfer it.
