Solution 1Recommended

Uninstall Older 32-bit Microsoft Applications

Remove older 32-bit versions of Microsoft software, such as Project or Visio, that conflict with the 64-bit Office 2024 installation.

The most common cause of this error is attempting to install a 64-bit version of Office 2024 while older 32-bit Microsoft applications are still installed on the system. Microsoft does not support running 32-bit and 64-bit Office products simultaneously.

Open Windows Settings

Click the Start menu and select the 'Settings' gear icon, or press the Windows key + I on your keyboard.

Navigate to Installed Apps

Click on 'Apps' in the left-hand menu, then select 'Installed apps' or 'Apps & features' to view a list of all software on your computer.

Locate Conflicting Products

Scroll through the list and look for older versions of Microsoft Visio, Microsoft Project, or other standalone Office-related programs.

Uninstall the Applications

Click the three dots next to the conflicting application and select 'Uninstall'. Follow the on-screen prompts to remove the software completely.

Restart and Reinstall

Restart your computer to clear any lingering registry files, then run the Office 2024 installer again.

Solution 2

Install the 32-bit Version of Office 2024

Frequently Asked Questions

Why does the Office 2024 installer show a blank list of conflicting products?

This is a known quirk in the installer where it successfully detects an architecture mismatch (such as a 32-bit version of Visio) but fails to populate the application's name in the error prompt. You must manually check your installed apps to identify the culprit.

Can I run 32-bit Visio and 64-bit Office 2024 on the same computer?

No, Microsoft's Click-to-Run technology does not support installing 32-bit and 64-bit Office products on the same computer. You must either upgrade Visio to 64-bit or choose the 32-bit version for Office 2024.

What should I do if I do not have Visio or Project installed but still get this error?

Check for other standalone Microsoft applications such as older versions of Access Database Engine, SharePoint Designer, InfoPath, or even older leftover Office compatibility packs. Uninstalling these can often clear the conflict.
