Use the Correct Installation Method for Your License Type

The offline installation process differs significantly between home users and organizational customers. Ensuring you are using the correct method prevents configuration file errors.

Home users typically do not need to use PowerShell or a configuration.xml file. They can download an offline installer image directly from their Microsoft account. Organizational users must use the Office Deployment Tool (ODT) which requires precise XML configuration.

1
Identify your user type

Determine whether you are installing a Microsoft 365 Family/Personal subscription (Home) or an Enterprise/Business volume license (Organizational).

2
Download the correct installer package

For home users, log into your Microsoft account dashboard and select 'Download an offline installer' under the Install Office options. For organizations, download the latest Office Deployment Tool (ODT).

3
Verify the PowerShell path (Organizational Users Only)

If you must use PowerShell, ensure you have navigated to the correct folder using the 'cd' command. Your execution command should look like '.\setup.exe /configure configuration.xml' making sure the filename matches your XML file exactly.

Check Hidden File Extensions: A common cause for this error is Windows hiding file extensions. Your file might accidentally be named 'configuration.xml.txt'. Enable 'File name extensions' in the View tab of File Explorer to verify.

Frequently Asked Questions

Why does PowerShell say my configuration file cannot be found?

This error typically occurs if your PowerShell terminal is not operating in the same directory as the configuration file, if the filename is misspelled in your command, or if the file has an incorrect hidden extension like .txt.

Do I need the Office Deployment Tool (ODT) for a home PC?

No. Home users with Microsoft 365 Personal or Family subscriptions should download the offline installer directly from their Microsoft account dashboard, completely bypassing the need for ODT or configuration files.

How do I ensure PowerShell runs setup.exe from the current folder?

In PowerShell, you must prefix the executable with '.\' to specify the current directory. The correct command syntax is usually '.\setup.exe /configure configuration.xml'.
