How to use and install Office 365 Offline Installer?

There is a considerable difference between the installation file for any other applications in the Office 365 suite. The Office 365 offline installer comes in the form of an IMG file. To run the installation files in the IMG format, you would need to mount it on the operating system.

If you have Windows 10 or 8.1, you would not need to depend upon the third party option for mounting the IMG file on the operating system. These operating systems come with an out of the box support for IMG file.

Here are the steps involved in mounting the IMG file on your Windows 10 or Windows 8.1 device –

  • Go to the file explorer on your device and locate the installer file that you just downloaded.
  • Right-click on the IMG file and click on Mount option among the contextual menu.
  • You will now be able to find the installer on your device.
  • Click on Setup option to begin installing your Office 365 Business Premium subscription.
  • Follow the instructions to install your Office 365 carefully

Once the application is installed, you can sign in to the service with your email ID. Please note that the email ID should be the same as the one you have used to sign up and subscribed to Office 365.

If you are on Windows 7 or another operating system, you will need to rely upon the third party application to mount the IMG file on your computer. One of the most popular IMG mounting software options would include Virtual CloneDrive. You can choose any of your favorite IMG mounting software options on your device.

How to use Office 365 Business Premium Offline Installer?

If you have subscribed to Business Premium plan or any of the business plans under Office 365, the method will not work. Since you have opted for the business plan, the installation will be possible only through the Office Deployment Tool. You can opt for the offline installer either through command prompt or script.

The method is a little complicated.

Here is how you would be able to do it –

  • Create a new folder on your computer with the name Office 365. You can name it to office offline or anything else at your preference.
  • You can download the Office Deployment tool from this link.
  • Run the Office Deployment tool and extract the files into the newly created folder above.
  • Find the files inside the folder that you have just launched.
  • The folder will now have two files – exe and configuration.xml
  • Open the XML file in Notepad and edit it. Make the changes as outlined here –

<Add SourcePath="C:Office365" OfficeClientEdition="64" Channel="Monthly">

<Product ID="O365ProPlusRetail">

<Language ID="en-us" />



<Updates Enabled="TRUE" Channel="Monthly" />

<Display Level="None" AcceptEULA="TRUE" />

<Property Name="AUTOACTIVATE" Value="1" />


Please note that you would need to make the changes as shown in the Red color. The C:Office365 refers to the folder you created in the first step. 64 in the above code refers to the 64-bit architecture. If you are on a 32-bit machine, change it to 32. The product ID as in the above code will be O365BusinessRetail for Office 365 Business plan. For the other programs, you will use O365ProPlusRetail.

  • Once the code is changed, save it.
  • Now, launch Command Prompt, and run the following commands pressing Enter it after each command.
cd c:Office365

setup.exe /download configuration.xml
  • The download will now begin. Wait till the download is completed. A new folder will be created by the name Office in the new folder you created.
  • Once the installer is downloaded, execute the following command to begin the installation
setup.exe /configure configuration.xml

Once the installation is complete, you will need to get it activated through your IT administrator. Your admin should be able to activate the copy with the volume license key.  In fact, this is the only way you would be able to use the offline installer on the Office 365 Business Premium plan.

A slight variation of the above steps would include the following steps –

  • Download and install the Office Deployment Tool as in the above steps.
  • Create a folder named Office
  • Extract and save the files from the Deployment Tool in the newly created folder.
  • Open Notepad on your computer
  • Enter the following code and save the file.

  <Add OfficeClientEdition="64">

    <Product ID="O365BusinessRetail">

      <Language ID="en-us" />



  • Save the above file as XML
  • Launch RUN dialog box and execute the following command
c:odtsetup.exe /download installOfficeBusRet64.xml
  • Accept UAC if prompted to do so.
  • You should find the folder named c:ODTsetup.exe. The offline installation files for your Office 365 Business plan will begin downloading into your newly created folder.

Wait patiently till the download is completed. Please note that the installation progress will not be available for your needs. You will get the confirmation that the installation is complete when the dialog box closes on its own.

Once the download is complete, begin installation using the following command through the dialog box –

 c:odtsetup.exe /configure installOfficeBusRet64.xml
