Microsoft Project is a project management application that’s a part of the MS Office software series, but it’s not included with the suite. Thus, users need to install MS Project separately. However, the following error message can pop up for some users when attempting to install Project: “We’re sorry, Office Click-to-Run installer encountered a problem because you have these Windows Installer based Office programs installed on your computer… Click-to-Run and Windows Installer editions don’t get along on for this version, so you can only have one type installed at a time.”

That error arises when users try to install Microsoft Project with the Click-to-Run technology. However, Windows Installer Office software is already installed when they try to install it. Therefore, a compatibility issue aries.

How to Fix Project’s Click-to-Run Installer Error

1. Uninstall the MSI Office Version

  1. Uninstalling all Windows Installer MSI Office software before installing Microsoft Project will usually fix the issue for most users. Press the Windows key + R hotkey.
  2. Then open the Windows uninstaller by entering ‘appwiz.cpl’ in Run and clicking OK.The uninstaller window microsoft project won't install
  3. Select the MSI Office software and click Uninstall.
  4. Select the Yes option to confirm and uninstall the software.
  5. Restart Windows after uninstalling the MS Office software.
  6. Then try installing Microsoft Project.

Removing MS Office with the Windows uninstaller might leave some leftover files and registry entries. Thus, it might be better to more thoroughly remove MS Office software with either a third-party uninstaller or the Microsoft Support and Recovery Assistant. Click the blue Download button on the Uninstall Office page to save the setup wizard for the Microsoft Support and Recovery Assistant. Install the software with the setup wizard, and open its window.
