Fix Microsoft Project Not Opening and Safe Mode Error
Question details
Microsoft Project fails to open from the Start menu or executable file, displaying a Safe Mode message before freezing or crashing.
- Product
- Microsoft Project
- Device & OS
- Windows 10
- Scenario
- Attempting to launch Microsoft Project or other Microsoft 365 applications from the desktop.
- Observed behavior
- The application displays a Safe Mode prompt but does nothing further. Other Office applications on the same computer may also experience startup failures or template errors.
Ensure you have administrator privileges on your Windows computer, as you may need to create a new user profile or run a system-level repair on Microsoft Office.
Create a New Windows User Profile
If multiple Office applications are failing to start, your current Windows user profile settings might be corrupted. Testing in a new profile isolates the issue.
Windows user profile corruption can cause persistent application failures that standard repairs cannot fix. Creating a new local profile provides a fresh environment to run Microsoft Project.
Click the Start menu and select the gear icon to open Settings. Navigate to Accounts, then select Family & other users from the left pane.
Click 'Add someone else to this PC'. Follow the on-screen prompts to create a new local Windows account or sign in with a different Microsoft account.
Sign out of your current Windows session. Sign in using the newly created user profile, locate Microsoft Project in the Start menu, and attempt to open it.
Run Microsoft Office Online Repair
Use the built-in Windows repair tool to fix corrupted Office installation files that might be causing Safe Mode loops.
Reset the Word Normal.dotm Template
If Microsoft Word is also failing alongside Project, clearing its default template can resolve related shared Office startup errors.

Frequently Asked Questions
Why does Microsoft Project keep opening in Safe Mode?
Safe Mode is a diagnostic state triggered when the application detects corrupted startup files, faulty add-ins, or damage in the Windows user profile. It is designed to help you launch the program with minimal features so you can troubleshoot.
Will reinstalling Microsoft Project fix the Safe Mode error?
Reinstalling might help if the application files themselves are corrupted. However, if the issue stems from a corrupted Windows user profile, reinstalling will not resolve the problem until a new profile is created.
Can I keep my personal files if I create a new Windows user profile?
Yes. Once you confirm that Microsoft Project works on the new user profile, you can manually copy your documents, pictures, and desktop files from the old profile directory (located in C:\Users) into your new profile folder.
