- Scenario
- Opening any Microsoft 365 desktop application, such as Word or Excel, from the Start menu or desktop.

Uninstall the Conflicting Microsoft 365 Dashboard App
Resolve installation conflicts by removing the unnecessary Microsoft 365 dashboard application if you already have the full desktop suite installed.
Windows sometimes installs a lightweight 'Microsoft 365 (Office)' dashboard app alongside your full desktop suite. Having both installed can create a conflict, causing the full applications to crash or trigger a repair prompt.
Click the Start menu and select the gear icon to open Settings, or press Windows Key + I.
Click on 'Apps' and select 'Apps & features' from the left sidebar.
Scroll down the list of installed programs and look for 'Microsoft 365 (Office)'. Ensure your main full suite (e.g., 'Microsoft 365 Apps for enterprise') is also listed.
Click on the 'Microsoft 365 (Office)' dashboard app and select 'Uninstall'. Follow the on-screen prompts to remove it.
Restart your Windows PC to clear any lingering conflicting background processes, then launch Word or Excel to test if the error is resolved.

Frequently Asked Questions
What is the Microsoft 365 (Office) app?
The Microsoft 365 (Office) app is a lightweight dashboard or hub application installed by default on Windows. It is designed to help users access Office files online or act as a shortcut hub, but it is unnecessary and often causes conflicts if you already have the full desktop suite installed.
Why does clicking 'Repair Now' only work temporarily?
The 'Repair Now' button attempts a quick fix in your current active session, which may allow the app to launch once. However, if there is a deeper installation conflict between the dashboard app and the full suite, the underlying issue remains and the error will return the next time you open the program.
Will uninstalling the dashboard app delete my personal files?
No. Uninstalling the 'Microsoft 365 (Office)' dashboard app only removes the software interface. All your locally saved documents, spreadsheets, and presentations will remain safe and untouched on your hard drive.
