Fix Adobe Acrobat Reader Crashing After Cloud Sync on Windows Phone
Question details
Adobe Acrobat Reader crashes or becomes completely inaccessible after attempting to sync with cloud storage.

- Product
- Adobe Acrobat Reader
- Device & OS
- Windows Phone 8
- Scenario
- Connecting the PDF reader application to Adobe Acrobat.com cloud storage to synchronize documents.
- Observed behavior
- The application repeatedly crashes or locks up. Reinstalling the app only restores functionality if the cloud synchronization feature remains disabled.
Ensure you know your Adobe account credentials, as you will need to sign out and may need to contact Adobe support to identify corrupted files in your cloud storage.
Disconnect Cloud Account and Perform Clean Reinstallation
Stop the app from syncing potentially corrupted cloud data by disconnecting your account and reinstalling the software cleanly.
When the PDF reader attempts to process a corrupted file from the cloud, it can trigger an infinite crash loop. Isolating the app from the cloud is the most effective way to restore its basic functionality so you can continue reading local files.
If you can briefly open the app without it crashing, immediately sign out of your Adobe Acrobat.com account. Afterward, completely restart your Windows Phone device.
Uninstall the Adobe app from your device to remove corrupted caches. Go to your phone settings to clear any residual app data, then reinstall the latest version from the Windows Phone Store.
Navigate to your phone's system settings and ensure that your device operating system is fully updated to avoid any background compatibility bugs.
Launch the newly reinstalled app but do not sign in to your cloud account. Keep cloud synchronization disabled until Adobe Support can review your account for corrupted files.

Frequently Asked Questions
Why does Adobe Acrobat Reader crash only when cloud sync is enabled?
This usually happens when a specific PDF file stored in your Adobe cloud account is corrupted or improperly formatted. When the app attempts to download and index this file during sync, the rendering engine fails, resulting in an immediate crash.
Will I lose my PDF files if I uninstall the app to fix the crash?
No, your cloud-synced files are securely stored on Adobe's servers and will remain intact. However, any locally saved PDFs on your phone that haven't been backed up to the cloud or another location may be deleted during the uninstallation process.
Can I use a different application to read PDFs on my mobile device?
Yes, there are several alternative PDF readers and comprehensive office suites, such as WPS Office, available in the app store that can open standard PDF files efficiently without relying on Adobe's specific cloud synchronization platform.
How do I fix the corrupted cloud file causing the crash?
Because the file is located on Adobe's servers, you must log into your account through a desktop web browser to identify and delete the corrupted file, or reach out to Adobe Support to have them investigate and reset your cloud storage status.
