Activation by product type

Windows

Open Settings > System > Activation, choose Change product key and enter your key. Full walkthrough: installing and activating Windows 11.

Microsoft Office, Visio and Project

Redeem the key at setup.office.com with your Microsoft account, then install from your account’s Services & subscriptions page. Uninstall any other Office version first.

Autodesk

Accept the subscription assignment sent to your email, sign in to Autodesk Account at manage.autodesk.com and download the product from All Products and Services.

Avast, Webroot and McAfee

Download from the publisher’s official site (avast.com, webroot.com/safe or mcafee.com/activate) and enter the activation code from your order message.

Common problems

My Windows key says it's invalid. What should I check?
Make sure the installed edition matches the key (Home key for Windows 11 Home, Pro key for Pro), that you typed all 25 characters, and that the PC is online. Then open Settings > System > Activation > Troubleshoot.
Office says the product key has already been used.
Retail Office keys are redeemed once, to one Microsoft account. Sign in at account.microsoft.com with the account you used the first time and install Office from Services & subscriptions.
I bought the Windows version of Office but I have a Mac.
Contact us before redeeming the key. Once a key has been redeemed to a Microsoft account it can't be exchanged.
My antivirus code isn't accepted.
Check that you installed the matching product (for example Avast Premium Security, not Avast Free Antivirus) and that you're entering the code in the correct app.
I sent my order but haven't received my key yet.
Keys are sent in the same WhatsApp chat once payment is confirmed. If you've paid and still don't have it, reply in the chat with your order reference.
