Post By pushkar default No Comments

Facing Launch Issues with Office 2024 and Project 2024 Side-by-Side?

If you’ve recently installed Microsoft Office 2024 Professional Plus and Microsoft Project 2024 Professional on the same PC and discovered they won’t open together, you’re not alone. Users across forums, IT support desks, and even Microsoft’s community boards are reporting compatibility issues—specifically, double-clicking on one app causes the other to crash or not open at all.

This blog post walks you through the registry fix that Microsoft forgot to include in their official documentation. We’ll also discuss why this issue happens, how to fix it safely, and how to prevent it in the future.

Why Office 2024 and Project 2024 Conflict

Common Causes of the Conflict

When both Office and Project are installed:

  • They may share the same licensing service (especially if not volume-licensed).

  • The Click-to-Run configuration overlaps in the Windows Registry.

  • Shared DLL files or version mismatches prevent proper coexistence.

This often leads to scenarios where Office apps won’t open after Project is installed, or vice versa.

The Registry Fix Microsoft Forgot

Important: Backup Your Registry First

Before making changes, create a system restore point and backup your registry:

  1. Press Win + R, type regedit, and hit Enter.

  2. In the Registry Editor, click File > Export to save a backup.

Step-by-Step Registry Fix

  1. Open the Registry Editor (regedit).

Navigate to:

 HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ClickToRun\Configuration

  2. Locate the key:

    • SharedComputerLicensing (If not present, create a DWORD (32-bit) value).

    • Set the value to 1.

Next, navigate to:

 HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\16.0\Common\InstallRoot

  1.  (Replace 16.0 with 24.0 if that’s the version tag used for Office 2024.)

  2. Modify (or add) a String Value:

    • Name: Path

    • Value: C:\Program Files\Microsoft Office\root\Office16

  3. Close the registry and restart your system.

This tells Windows to recognize Office and Project as separate but compatible programs.
