    Did you purchase a preinstalled Office product? In that case, the seller should be able to provide you with details on how to install and activate.

    If you purchased Office separately, use your account at https://account.microsoft.com/services .

    For more, see https://support.microsoft.com/en-us/office/lifecycle/officeinstall/download-install-or-reinstall-microsoft-365-or-office-2024-on-a-pc-or-mac.

    Follow https://support.microsoft.com/en-us/office/lifecycle/officeinstall/download-install-or-reinstall-microsoft-365-or-office-2024-on-a-pc-or-mac#sign-in-to-download-microsoft-365-or-office-2024-on-a-pc

    Sign in to download Microsoft 365 or Office 2024 on a PC

    Go to m365.cloud.microsoft/apps. If you're not already signed in, select Sign in, and then select the Install apps drop-down.

    Sign in with the account you associated with this version of Microsoft 365. This account can be a Microsoft account, or a work or school account.

    After signing in, follow the steps that match the type of account you signed in with.

    You signed in with a Microsoft account                                  Seperator

    1. From the Microsoft 365 Apps page select Install apps.

    1. Select Install (or depending on your version, Install apps>).

    You signed in with a work or school account                                  Seperator

    1. From the home page select Install apps. (Or, you might need to select Apps from the left navigation pane, and then select Install apps.)

    1. Select Microsoft 365 apps to begin the installation.

    The 64-bit version is installed by default unless Microsoft 365 or Office detects you already have a 32-bit version of Microsoft 365 or Office (or a stand-alone app such as Project or Visio) installed. In this case, the 32-bit version of Microsoft 365 or Office will be installed instead. To change from a 32-bit version to a 64-bit version or vice versa, you need to uninstall Microsoft 365 first (including any stand-alone Microsoft 365 apps you have such as Project of Visio). Once the uninstall is complete, sign in again to m365.cloud.microsoft/apps and select Install apps. From the Install apps window select the language and version you want (64 or 32-bit), and then select Install. (See Install Visio or Install Project if you need to reinstall those stand-alone apps.)

    This completes the download of Microsoft 365 to your device. To complete the installation and activation steps, follow the prompts in the following install and activation sections.

    Tip

    Don't see an install option after signing in? There could be an issue with your account. Select the Need help? tab from above and review the solutions under Account questions.

    Install Microsoft 365 or Office 2024 on a PC

    1. Depending on your browser, select Run (in Microsoft Edge or Internet Explorer), Setup (in Chrome), or Save File (in Firefox). If you see the User Account Control prompt that says, Do you want to allow this app to make changes to your device? select Yes. The install begins.
    2. Your install is finished when you see the phrase, "You're all set! Office is installed now" and an animation plays to show you where to find Microsoft 365  applications on your computer. Select Close.

    If Microsoft 365 came preinstalled with the new computer, open Word and sign in to claim it; if you received a product key, redeem that key first and then install the apps.

    If Microsoft 365 is already on the computer

    1. Select Start, type Word, and open it.
    2. At the activation screen, sign in with the Microsoft account you want associated with the purchase.
    3. Follow the prompts and accept the license agreement.

    For an included digital purchase, the license is transmitted to the computer, so a printed product key may not be provided. Signing in adds the product to your Microsoft account for future installation and subscription management.^1^

    If you received a 25-character product key

    1. Go to Office.com/setup.
    2. Sign in with an existing Microsoft account or create one.
    3. Enter the product key without hyphens, if prompted.
    4. Complete the redemption process. This links the purchase to that Microsoft account.^2^

    Keep track of the account used here—you will use it to install, activate, or reinstall Microsoft 365. If the site says the key has already been used, do not enter it again; sign in using the Microsoft account with which it was originally redeemed.^2^

    Download and install the apps

    After claiming the preinstalled purchase or redeeming the key:

    1. Go to Microsoft 365 Apps.
    2. Sign in with the Microsoft account associated with the purchase.
    3. Select Install apps in the upper-right corner.
    4. Select Microsoft 365 apps or Install.
    5. When the download finishes, open the setup file:
      • In Microsoft Edge, select Run.
      • In Chrome, select Setup.
      • In Firefox, select Save File, and then open the downloaded file.
    6. If Windows asks whether the installer may make changes, select Yes.
    7. Wait for “You’re all set! Office is installed now,” and then select Close.^3^

    Finally, open Word from the Start menu and sign in with the same Microsoft account if prompted. If an Activation Wizard appears, complete its prompts.^1^
