“Microsoft Project Has Stopped Working” in Project Professional

If you’re working with Microsoft Project Professional and find that the application freezes or crashes when opening a project from Project Center, you’re not alone. This is a common issue, especially in environments integrated with Project Online or part of a broader Microsoft 365 setup. Whether you’re a project manager, a PMO analyst, or part of an IT support team, this guide walks through practical steps to help you identify and fix the problem.

Some users experience an issue where Project Professional freezes or crashes when opening a project from Project Center. This is often accompanied by the error message:

“Microsoft Project has stopped working”

If you’re seeing this error when launching or editing a project, the following steps can help you resolve it.

Start by contacting your internal IT team

Because this is a client-side application issue, your first step should be to speak with your internal IT support team. Some of the actions below may require administrator privileges, depending on your organisation’s security policies.

Run an online repair of Microsoft Project

A full Online Repair can resolve many problems related to corrupted installations or file conflicts. To perform the repair:

1. Open the Control Panel

2. Go to Programs and Features

3. Locate and select Microsoft Project

4. Click Change

5. Choose Online Repair and follow the prompts

This process reinstalls all Office files associated with Project and is more thorough than a quick repair.

Check for pending updates

If the issue persists after repair, it’s worth checking that your installation is fully up to date:

1. Open Project Professional

2. Go to File > Account

3. Under Product Information, click Update Options

4. Select Update Now

Updates often contain performance and stability improvements, and pending updates can cause compatibility issues, especially in environments using Project Online.

Understand how office updates are managed in your organisation

Depending on your IT configuration, Microsoft Office updates, including those for Project may be:

• Automatically installed

• Rolled out on a schedule

• Managed manually by IT

It’s a good idea to check with your IT team to understand your organisation’s update policy and ensure that Project receives critical patches as they are released.

Optional: Planning ahead for long-term stability

If issues are recurring or you’re using an older setup, it may be worth reviewing whether Project Professional is the best fit for your environment. Many organisations are now transitioning to Microsoft Planner (formerly Project for the Web) combined with Wellingtone Accelerator+, which offers:

• Simplified user experience

• Modern reporting and dashboards

• Microsoft Teams integration

• Co-pilot and AI readiness
