Fix Cannot Install Microsoft Project Professional 2024 on Windows 11
Question details
Users are unable to successfully install Microsoft Project Professional 2024 on their Windows 11 computers, especially after removing a previous version like Project 2021.
- Product
- Microsoft Project Professional 2024
- Device & OS
- Windows 11
- Scenario
- Installing or upgrading to a new version of Microsoft Project Professional on a Windows 11 system.
- Observed behavior
- The installation process fails or gets blocked due to leftover registry components from previous installations, or incompatible installation types (such as mixing MSI and Click-to-Run versions of Office applications).
Ensure that your Windows 11 system is fully updated to the latest version and verify that you have administrative privileges before attempting to run Microsoft uninstallation and recovery tools.
Use Microsoft Support and Recovery Assistant to Remove Leftovers
Completely clear out stubborn leftover files and registry entries from previous Project or Office installations that are blocking the 2024 installation.
Standard uninstallation via the Windows Control Panel often leaves behind residual registry keys and components. The Microsoft Support and Recovery Assistant (SaRA) tool performs a deep clean of these remnants, ensuring a clean slate for Project Professional 2024.
Visit the official Microsoft Support website and download the Microsoft Support and Recovery Assistant.
Launch the downloaded application and select 'Office' from the list of products, then choose 'I have Office installed, but I'm having trouble uninstalling it'.
Select the previous version of Project (e.g., Project 2021) or any other corrupted Office installations listed, and follow the on-screen prompts to remove them completely.
Once the removal process is complete, restart your Windows 11 PC and run the Microsoft Project Professional 2024 installer again.
Resolve MSI and Click-to-Run Installation Conflicts
Identify and remove conflicting Office installation types, as Microsoft prevents installing Click-to-Run products alongside MSI-based products.

Frequently Asked Questions
How do I know if my Office suite is MSI or Click-to-Run?
Open any Office application, such as Word or Excel, and navigate to File > Account. Look under the 'Product Information' section. If you see a button labeled 'Update Options', your installation is Click-to-Run. If the button is missing, you are using an MSI installation.
Can I install Project Professional 2024 if I have Office 2019 installed?
It depends on the installation type. Microsoft does not support installing products of different versions if they use overlapping or conflicting deployment technologies. Generally, you should ensure all your Microsoft productivity tools use Click-to-Run to avoid deployment errors.
Where can I find the installation error logs for Microsoft Project?
If the installation fails silently or with a generic error code, you can check the logs located in your system's Temp folder. Press Win + R, type '%temp%', and look for text files starting with 'SetupExe' or containing 'Office' to find specific error details.
