Set up Office Professional Plus 2024

For 1 Windows PC. Your delivery email has your product key; these are the steps to install and activate.

Before you begin

Checking these first avoids most installation and activation problems.

  • No other Office version is installed. Remove Microsoft 365, Office 2021 or earlier, and restart.
  • The PC is connected to the internet for the download, installation and activation.
  • You know whether Windows is 64-bit or 32-bit: Settings, System, About, System type. Most PCs are 64-bit.
  • Microsoft Teams is not part of this package. Install it separately from Microsoft if you need it.

Install and activate

Follow the steps in order.

Keep your product key private. Never post it or send the whole key by email.

  1. Remove other Office versions

    Uninstall Microsoft 365, Office 2021 or any earlier Office from Windows Settings, then restart. A leftover installation is the most common reason setup or activation fails.

  2. Install Office 2024

    Download Office with the link in your delivery email, run the installer and keep the internet connection on until it finishes. Choose 64-bit unless your Windows is 32-bit.

  3. Enter your product key

    Open Word or Excel, create a blank document, then go to File, Account, Change Product Key and type the key from your email.

  4. Activate online

    Close and reopen the app, choose online activation and follow the prompts. File, Account then shows Office as activated.

The fixes that resolve most cases for this product.

See all problems and fixes
Office shows the wrong version or asks for telephone activation

This happens when a key from an older Office (2016, 2019 or 2021) is still stored in Windows. Remove the old keys, then activate again online.

  1. Search for cmd, right-click Command Prompt and choose Run as administrator.
  2. Type: cd "C:\Program Files\Microsoft Office\Office16" and press Enter. If that folder does not exist, use C:\Program Files (x86)\Microsoft Office\Office16.
  3. Type: cscript ospp.vbs /dstatus and note the last five characters of each key listed.
  4. For each old key type: cscript ospp.vbs /unpkey:XXXXX, replacing XXXXX with those five characters.
  5. Run cscript ospp.vbs /dstatus again to confirm the old keys are gone, then enter your new key under File, Account, Change Product Key.
The Office installer stops or will not start

Confirm that every earlier Office version has been removed, including a separately installed OneNote, and restart the PC.

Keep the internet connection on during installation. If a firewall or antivirus is blocking the download, change its setting only for as long as the installation takes, then turn protection back on.

My key is not accepted

Type the key rather than pasting it, and check characters that look alike, such as 8 and B or 0 and D. Make sure the key is for the product and edition installed on the computer.

If it is still refused, email info@softwarekeysource.com with a screenshot of the message and your SKS reference.
