Fix PowerPoint Video Export Stopping at 60% and Requesting Sign-in
Question details
The user is unable to complete exporting a presentation to a video file due to the process freezing midway, accompanied by recurring authentication prompts and destination folder errors.
- Product
- Microsoft PowerPoint
- Device & OS
- not provided
- Scenario
- Exporting a slideshow presentation into a video format, both locally and outside of OneDrive.
- Observed behavior
- The video export process consistently halts at approximately 60%, repeatedly demands Microsoft account credentials, and displays an error stating the destination folder is unavailable.
Before attempting to repair your software or modify system settings, verify that your local hard drive has sufficient free space for the video file and ensure your presentation is saved as a backup.
Repair Your Microsoft Office Installation
Running the built-in Microsoft Office repair tool can fix corrupted application files that cause the export process to freeze or fail.
Microsoft Office includes an automated repair utility that scans for and resolves missing or corrupted core files. An Online Repair is generally the most effective way to restore export functionalities and fix recurring authentication glitches.
Press the Windows key, type 'Control Panel', and press Enter. Navigate to 'Programs', then click on 'Programs and Features'.
Scroll through the list of installed applications to find your Microsoft Office suite. Right-click on it and select 'Change'.
When the prompt appears, select 'Online Repair' (instead of Quick Repair) and click the 'Repair' button. Wait for the process to complete, then restart your computer.
Reset Office Registry Settings
Resetting the Office registry key clears out corrupted user preferences and account cache data that may trigger the repeated sign-in prompts.
Isolate the Issue Across Devices and Files
Testing on a different device or with a different file helps determine if the issue is specific to the current computer environment or the presentation itself.
Export Presentations to Video Smoothly with WPS Office
If Microsoft PowerPoint continues to freeze or demand sign-ins during video export, consider switching to WPS Office. It provides a lightweight, highly compatible alternative for creating and exporting presentations without the hassle of recurring Microsoft account glitches.
- 1. Download and Install WPS Office: Get the free WPS Office suite from the official website and install it on your device.
- 2. Open Your Presentation: Launch WPS Presentation and open your existing .pptx file directly, with zero formatting loss.
- 3. Export Your Video: Navigate to Menu > Export to Video to render your presentation smoothly without mandatory cloud sign-ins.

Frequently Asked Questions
Why does PowerPoint repeatedly ask for sign-in during video export?
This is often caused by a glitch in the Office account authentication token or a conflict with OneDrive synchronization. When PowerPoint attempts to save temporary files or access cloud-linked resources during export, the corrupted token triggers a continuous sign-in loop.
How can I back up the registry before resetting Office settings?
Open the Registry Editor, right-click the specific key you intend to modify (or 'Computer' for the whole registry), and select 'Export'. Choose a safe location on your computer to save the .reg file, which can be double-clicked later to restore the settings if needed.
What should I do if the destination folder is reported as unavailable?
First, ensure you are attempting to save the video to a local directory (like your Desktop or Documents folder) rather than a cloud-synced folder or an external drive that might have disconnected. You should also check the folder properties to confirm your user account has 'Write' permissions.
Does renaming the Office registry key delete my PowerPoint files?
No. Renaming or resetting the registry key only clears the application's configuration preferences, such as custom ribbons, recent file lists, and account cache. Your actual presentation files (.pptx) and personal data remain completely safe.
