Office for homeOffice for business

Step 1. Download the offline installer from your account portal

Important: Before you begin, make sure your PC or Mac meets the system requirements.

  1. Select the download button below:

    Download

    Note: If you're trying to install Microsoft 365 that you got through your work or school and you already signed in with your work or school account, don't follow these instructions. Select the Office for business tab from above instead.

  2. In the Install window, select Offline installer from the Choose a version drop-down.

  3. Select the language you want to install the Microsoft 365 apps in. Select Install.

  4. When you're prompted, from the bottom of your browser window, select Save (in Edge), Open (in Internet Explorer), Open when done (in Chrome), or Save File (in Firefox). The file will begin downloading on your PC.

  5. Once the download is complete, locate the Download folder and open it. Double-click the O365HomePremRetail.img file. If prompted, select Open.

  6. This should open a virtual drive window. If there isn't a virtual drive window after opening the IMG file, open File Explorer and locate the new virtual drive, for example (D:). This drive contains the Microsoft 365 installation files. Double-click the virtual drive to open it. If you don't see the new drive, locate the image file you downloaded and double-click it again. The new drive should appear in your directory.

    Note: If you already have a drive labeled (D:), Microsoft 365 creates a virtual drive with the next available letter, which would be (E:) (as shown in the next step below).Save the image: You can also choose to save a copy of this virtual drive to a thumb drive or disc for later use.

Step 2. Install Office

  1. Open the Office folder in the virtual drive, and then select either the Setup32.exe to install the 32-bit version of Microsoft 365, or Setup64.exe to install the 64-bit version to begin the offline installation. If you're not sure which version is right for you, see Choose the 64-bit or 32-bit version of Office.

    Select the virtual drive which may be named D or the next available letter

    When you see the message, You're all set, you can access your Microsoft 365 applications.

  2. After your Microsoft 365 installation is complete, you need to activate Microsoft 365. Be sure you're connected to the Internet and then open any Office application, such as Word or Excel.

    In most cases, Office is activated once you start an application and after you click Accept to agree to the License terms. If you need activation help, see Activate Office.

  3. After activating Office and before you start using it, make sure you have the latest update.

    In any Microsoft 365 app, for example Word, open a new or existing document, then select File > Account.

    From the Update Options drop-down list box, select Update Now.

    Select Update Now for the Update Options drop-down

Note: If you were installing a non subscription Office product, such as Office 2024, the license for that product will update soon after the install is completed.

If you have a Microsoft 365 for business product you can use the Microsoft 365 Deployment Tool (ODT) to download and install Microsoft 365 or Microsoft 365 offline. The tool is designed for enterprise environments and runs from the command line, so the steps are more complicated--but they'll still work for installation on a single device.

You must have a Microsoft 365 or Microsoft 365 license assigned to you to install and activate the Microsoft 365 apps. To check if you have one, see What Microsoft 365 business product or license do I have?

Step 1 - Download and install the Office Deployment Tool

  1. Create a folder on your hard drive and name it ODT. For this example, we'll create it on the c:\ drive, like so: c:\ODT.

  2. Download the Microsoft 365 Deployment Tool from the Microsoft Download Center. Select Save As and save it to your downloads folder.

  3. In your downloads folder, double-click the Office Deployment Tool exe file to install it.

  4. If you see the User Account Control prompt that says, Do you want to allow this app to make changes to your device?, click Yes.

  5. Accept the Microsoft Software License Terms, and then click Continue.

  6. In the Browse for Folder dialog, select the ODT folder you created in earlier, and then click OK.

Step 2 - Download and install Office

The drop-down list below contains detailed steps that show how to download and install the 32-bit or 64-bit version of Microsoft 365 Apps for enterprise or Microsoft 365 Apps for business.

If you have a Microsoft 365 Apps for business or Microsoft 365 Business Standard plan, you need to download the Microsoft 365 Apps for business version. For all other plans, download the Microsoft 365 Apps for enterprise version. See the following if you're not sure which version to install:

Step 1: Install the 32-bit version of Microsoft 365 Apps for enterprise

  1. Open Notepad on your computer.

  2. Copy and paste the following into a blank text file in Notepad:

    <Configuration>
  <Add OfficeClientEdition="32">
    <Product ID="O365ProPlusRetail">
      <Language ID="en-us" />
    </Product>
  </Add>  
</Configuration>

    Note: The <Language ID> in the code above is for the English version "en-us". You need to change what's between those quotes if you want to download Office in a different language. If you're not sure what that is, use the URL for this topic to see your language ID, for example, "support.office.com/<this is your language ID>/article". In the text you just copied, replace "en-us" in this line, <Language ID="your language ID" />.

  3. Save the file as installOfficeProPlus32.xml in the ODT folder.

  4. Click Start, type run, and then select the Run Desktop app to open it.

  5. In the Run dialog, type the following exactly as shown below.

    • c:\odt\setup.exe /download installOfficeProPlus32.xml

    Click OK.

  6. If you see the User Account Control prompt that says, Do you want to allow this app to make changes to your device?, click Yes.

  7. A blank dialog box appears with c:\ODT\setup.exe in the title bar. The Office installation files should start downloading to the ODT folder on your computer.

    It can take a while to finish downloading and it may look like nothing is happening while the files are downloading. You'll know the installation is complete once the dialog box closes on its own, and a new folder called Office appears in the ODT folder you created earlier.

    After the files have finished downloading, open the Run dialog box again. This time type the following.

    • c:\odt\setup.exe /configure installOfficeProPlus32.xml

    Click OK.

  8. If you see the User Account Control prompt that says, Do you want to allow this app to make changes to your device?, click Yes.

    The install should begin.

Step 2: Activate and update Office

  1. After your Office installation is complete, you need to activate Office. Be sure you're connected to the Internet and then open any Office application, such as Word or Excel.

  2. Next, open an existing document or create a new document and select File > Account. Office should automatically activate.

  3. After you activate Office and before you start using it, make sure you have the latest updates. In the same document, select Update Options and in the drop-down list box, select Update Now.

    Select Update Now for the Update Options drop-down

    If nothing happens, close the application and repeat steps 2 and 3 to update Office from the Account page.
