Question details

The user is attempting to launch Microsoft PowerPoint but encounters a "Repair Now" prompt. After clicking the option, the application still fails to work or open properly.

Product
Microsoft PowerPoint
Device & OS
Windows
Scenario
Launching the PowerPoint application to create, view, or edit presentation files.
Observed behavior
PowerPoint displays a "Repair Now" error dialog box upon startup and subsequently crashes or refuses to open.
Before you start

Check whether other Microsoft Office applications like Word or Excel are also displaying the same error, as this indicates a system-wide Office installation issue rather than an isolated PowerPoint glitch.

Solution 1Recommended

Run an Online Repair for Microsoft Office

Use the Windows Control Panel to perform a comprehensive Online Repair, which replaces corrupted Office installation files that trigger the "Repair Now" loop.

Clicking the "Repair Now" button in the error prompt often fails to resolve underlying corruption. Running the Online Repair tool directly from the Control Panel is a more thorough method that redownloads and fixes the broken application files.

1
Open Control Panel

Press the Windows key + R to open the Run dialog, type 'control panel', and press Enter.

2
Navigate to Programs

Click on 'Programs' and then select 'Programs and Features' to view your installed applications.

3
Modify the Microsoft Office Installation

Scroll down to find Microsoft Office in the list. Right-click on it and select 'Change'.

4
Execute Online Repair

In the pop-up window, choose 'Online Repair' (instead of Quick Repair) and click the 'Repair' button. Follow the on-screen prompts to complete the process.

Internet Connection Required: Online Repair requires an active internet connection and may take somewhat longer than a Quick Repair, but it has a much higher success rate.
Free Microsoft Office alternative

Use WPS Presentation as a Free Alternative When PowerPoint Fails

  1. 1. Download and Install: Download WPS Office for free from the official website and run the quick installer.

Frequently Asked Questions

Why does PowerPoint keep saying 'Repair Now'?

This error is usually caused by corrupted Microsoft Office installation files, conflicting third-party add-ins, or a pending Windows update that disrupted the Office registry keys.

Will repairing Microsoft Office delete my PowerPoint files?

No. Running an Online Repair or Quick Repair only fixes the application's installation files. Your personal presentations (.pptx files) stored on your computer or OneDrive will remain safe and unaffected.

What should I do if the Online Repair tool fails?

If Online Repair doesn't work, you may need to completely uninstall Microsoft Office using the official Microsoft Support and Recovery Assistant (SaRA) tool, and then reinstall the suite from your Microsoft account.

Does clicking the 'Repair Now' button in the prompt actually work?

Often, clicking the button inside the error prompt fails to resolve the underlying corruption. It is highly recommended to perform a manual Online Repair through the Windows Control Panel instead.
