Fix Microsoft Project 2016 Installation Conflict with Microsoft 365
Question details
The user is unable to install Microsoft Project 2016 on a computer that already has Microsoft 365 installed due to installer compatibility issues.
- Product
- Microsoft Project 2016, Microsoft 365
- Device & OS
- not provided
- Scenario
- Attempting to install a standalone version of Project 2016 alongside a current Microsoft 365 subscription installation.
- Observed behavior
- Project 2016 fails to install because its MSI (Windows Installer) format conflicts with the Microsoft 365 Click-to-Run installation.
Verify that you have administrative privileges on your computer, as deploying applications via the Office Deployment Tool requires elevated permissions.
Deploy the Click-to-Run Edition of Project 2016
Resolve the installer conflict by deploying the Click-to-Run version of Project 2016 using the Microsoft Office Deployment Tool (ODT).
Microsoft Office does not allow mixing MSI (Windows Installer) and Click-to-Run installations on the same system. Because Microsoft 365 uses Click-to-Run, any additional Office products, such as Project 2016, must also use the Click-to-Run technology.
To install the Click-to-Run version of Project 2016, you will need to use the Office Deployment Tool along with a custom configuration XML file.
Navigate to the official Microsoft Download Center and download the Office Deployment Tool executable.
Run the downloaded executable file to extract the ODT components (setup.exe and sample XML files) into a designated folder on your computer.
Visit config.office.com to access the Office Customization Tool. Configure your deployment settings for Project 2016 (Volume License) and export the settings as a configuration.xml file into the same folder as your ODT files.
Open Command Prompt as an administrator, navigate to the folder containing your ODT files, and execute the command 'setup.exe /configure configuration.xml' to begin the installation.

Frequently Asked Questions
Can I install an MSI version of Visio or Project alongside Microsoft 365?
No. Microsoft does not support mixing MSI (Windows Installer) and Click-to-Run installation types on the same computer. You must use the Click-to-Run version for all Office products.
What is the Office Deployment Tool (ODT)?
The Office Deployment Tool is a command-line utility provided by Microsoft that allows IT administrators to download, configure, and deploy Click-to-Run versions of Office, Project, and Visio.
Where can I generate the configuration XML file for the installation?
You can use the official Office Customization Tool at config.office.com to easily select your product, licensing, and update preferences, and then export it as an XML file.
Will uninstalling Microsoft 365 allow me to install the MSI version of Project 2016?
Yes. If you completely uninstall the Click-to-Run installation of Microsoft 365, the system will allow you to install the MSI version of Project 2016. However, this means you will no longer have access to your Microsoft 365 applications.
