Scenario
Deploying Microsoft Project and Visio 365 alongside Microsoft 365 Standard using a specific regional language pack (en-GB).

Solution 1Recommended

Reconfigure Deployment using the Office Customization Tool

Using the web-based Office Customization Tool (OCT) ensures your deployment XML file has the correct product IDs and language identifiers for Project and Visio.

Manual XML configuration errors are the most common cause of deployment failures for standalone products like Project and Visio. Generating a fresh configuration file using Microsoft's official tool will accurately map the requested products to the en-GB language pack.

1
Access the Office Customization Tool

Open your web browser and navigate to config.office.com to access the Microsoft Office Customization Tool.

2
Select the correct Products

Choose the appropriate architecture (32-bit or 64-bit). Under the 'Products' section, explicitly select your specific versions of Project and Visio (e.g., ProjectProRetail or VisioProRetail).

3
Configure the Language Setting

Scroll to the 'Language' section. Select 'English (United Kingdom)' as the primary language. Do not select MatchOS if it consistently defaults to en-US on your environment.

4
Export and Deploy

Click 'Export' to generate the new XML configuration file. Use the Office Deployment Tool (ODT) in your command line with this new file (e.g., setup.exe /configure newconfig.xml) to install the applications.

Frequently Asked Questions

Why does Microsoft 365 Standard install in en-GB but Project fails?

Project and Visio operate on separate deployment identifiers (like ProjectProRetail). They may require explicitly matched language parameters in the XML configuration file, independent of the main Microsoft 365 suite settings.

What is the MatchOS setting in Office deployment?

MatchOS is an XML configuration attribute that instructs the Office Deployment Tool to install the Office applications using the same default language as the host operating system.

Where can I find the Office Customization Tool?

The Office Customization Tool is a free, web-based service provided by Microsoft at config.office.com. It allows administrators to dynamically generate and export precise configuration XML files for deployment.

Can I change the display language of Visio after installation?

Yes, you can change the display and proofing language at any time by navigating to File > Options > Language within the Visio application and downloading the desired language pack from Microsoft.
