Question details
The user needs to bypass an installation conflict preventing Microsoft Project Professional 2019 from installing on a machine with Microsoft 365 Enterprise.

- Product
- Project Professional 2019 / Microsoft 365
- Device & OS
- not provided
- Scenario
- Attempting to install Microsoft Project Professional 2019 from Azure alongside an existing Microsoft 365 Enterprise installation.
- Observed behavior
- The installation fails and throws error code 30204-44 due to incompatible installation technologies or versions between the products.
Ensure you have administrator privileges on your computer and download the latest Office Deployment Tool from the official Microsoft Download Center.
Use the Office Deployment Tool with an XML Configuration
Bypass the version and technology conflict by deploying Project 2019 using the Office Deployment Tool (ODT) alongside a customized XML configuration file.
Error 30204-44 typically occurs when trying to mix Click-to-Run and Windows Installer (MSI) technologies, or when mixing incompatible product versions. The Office Deployment Tool allows you to override standard installation barriers by explicitly defining how the products should coexist.
Create a new folder on your desktop. Run the downloaded Office Deployment Tool executable and select the newly created desktop folder to extract its files into.
Use the web-based Office Customization Tool to configure your deployment settings for Project 2019. Once configured, export the settings as an XML file and save it directly into the desktop folder you just created.
Click the Start menu, type 'cmd' into the search bar, right-click on 'Command Prompt', and select 'Run as administrator'.
In the Command Prompt window, use the 'cd' command to change the directory to your desktop folder (e.g., cd C:\Users\YourUsername\Desktop\NewFolder). Type 'setup.exe /configure exportedfilename.xml' (replace 'exportedfilename.xml' with your exact file name) and press Enter to begin the installation.

Switch to WPS Office for a Hassle-Free Productivity Experience
While the Office Deployment Tool is necessary to fix Microsoft's internal conflicts like error 30204-44, dealing with complex XML configurations can be frustrating.

It provides robust compatibility with standard Office formats without the complicated deployment requirements.
- 1. Download the software: Visit the official WPS Office website and click the free download button for your operating system.
- 2. Run the quick installation: Open the downloaded setup file and follow the simple on-screen prompts to install the suite in minutes without any configuration files.
- 3. Start working instantly: Open WPS Office and instantly access your existing Word, Excel, or PowerPoint files with perfect formatting preservation.

Frequently Asked Questions
What causes Microsoft Office installation error 30204-44?

Can I install Project 2019 and Microsoft 365 without using the Office Deployment Tool?
Usually, no. If the standard executable installer throws error 30204-44, you must use the Office Deployment Tool and a customized XML file to force the installation technologies to match.
