How to Fix Microsoft 365 Error 147-0 During Office Updates
Question details
Users need to resolve Error 147-0, which prevents Microsoft 365 applications from opening because the system incorrectly detects that programs are running during an update or repair process.
- Product
- Microsoft 365
- Device & OS
- Windows
- Scenario
- Attempting to update, repair, add, or remove Microsoft 365 applications via Windows Settings.
- Observed behavior
- The system displays Error 147-0 and asks the user to close applications that are already closed, causing the repair or update process to stall completely.
Ensure you have saved all ongoing work and have your Microsoft account login credentials readily available, as resolving this issue may require completely reinstalling your Office suite.
Force Close Office Processes via Task Manager and Retry Repair
Use the Windows Task Manager to manually terminate hidden background processes that are preventing the Microsoft 365 repair tool from completing.
Even when all Office application windows are visually closed, background services like Click-to-Run may still be active. These hidden processes trigger the warning that programs are still running.
Reboot your Windows PC to clear out any temporary memory states or crashed application threads.
Press Ctrl + Shift + Esc on your keyboard, or right-click the Windows taskbar and select 'Task Manager'.
Scroll through the 'Processes' tab to find any Microsoft Office related background processes (such as Microsoft Word, Excel, or Microsoft Office Click-to-Run Service). Right-click each and select 'End task'.
Navigate to Windows Settings > Apps > Installed apps. Search for Microsoft 365, click the three-dot menu (or Modify), select 'Online Repair', and follow the prompts.
Perform a Clean Reinstallation using the Uninstall Support Tool
If the Online Repair continues to stall and request programs to be closed, use Microsoft's dedicated uninstallation tool to clear the corrupted installation.

Frequently Asked Questions
What exactly causes Microsoft 365 Error 147-0?
This error is typically caused by background Office processes or Click-to-Run services getting stuck during an application update, installation, or removal. It blocks new applications from launching or the repair tool from completing.
Why does the Office repair tool say programs are open when they are visibly closed?
Windows may have hidden 'zombie' background processes related to Office still running in the background memory. You must manually terminate them via the Windows Task Manager.
Will reinstalling Microsoft 365 to fix this error delete my saved documents?
No. Uninstalling and reinstalling Microsoft 365 only removes the software applications themselves. Your locally saved documents, spreadsheets, and files synced to OneDrive remain completely safe and untouched.
