Question details
The user needs to resolve an issue where Microsoft Office applications fail to launch and display an error message regarding a previous failure.
- Product

- Device & OS
- not provided
- Scenario
- Attempting to launch any Microsoft Office application for regular use.
- Observed behavior
- The applications refuse to open, instead displaying a prompt stating that each app was unable to open the last time.
Ensure you have your Microsoft account login credentials available, as repairing or reinstalling Office may require you to sign back in to verify your active license.
Restart Your Computer
A simple system restart can often resolve background process conflicts or temporary glitches preventing Office apps from opening.
Ensure any open files in other running applications are saved to prevent data loss.
Click the Start menu, select the Power icon, and choose Restart. Wait for your computer to fully boot up before trying to launch the Office app again.

Frequently Asked Questions
Why does Microsoft Office say it couldn't open last time?
This error usually occurs if the application crashed unexpectedly during its previous session, an incompatible third-party add-in is malfunctioning, or the Office installation files have become corrupted.
Will running an Online Repair delete my existing documents?
No, running an Online Repair for Microsoft Office only replaces or fixes the software application files. Your personal documents, spreadsheets, and presentations are completely safe and will not be deleted.
What is the difference between Quick Repair and Online Repair?
Quick Repair runs entirely offline and fixes most common issues by rapidly replacing corrupted files. Online Repair takes longer and requires an active internet connection, as it performs a comprehensive fix by fully reinstalling the Office applications.
How can I launch Microsoft Office apps in Safe Mode to bypass errors?
Press and hold the CTRL key on your keyboard while double-clicking the Microsoft Word, Excel, or PowerPoint shortcut. Click 'Yes' when a prompt asks if you want to start the application in Safe Mode. This temporarily disables add-ins that might be causing the crash.
