Remove and Reinstall Using the Adobe Acrobat Cleaner Tool

Visit the official Adobe website and download the Adobe Acrobat Reader and Acrobat Cleaner Tool tailored for your operating system.
Launch the downloaded tool, accept the terms, and follow the on-screen prompts to completely remove the existing Reader installation.
Once the cleanup is finished and your computer is restarted, download the latest version of Acrobat Reader DC from Adobe's official page and install it.

Frequently Asked Questions
Why does the Acrobat Reader update say 'Uninstallation of the patch package is not supported'?
This error typically occurs when the original installation files or Windows registry entries are corrupted, which prevents the Windows Installer service from safely applying or rolling back the software patches.
Can I fix the update error without completely uninstalling the software?
You can attempt a built-in repair by opening Acrobat Reader, navigating to 'Help' in the top menu, and selecting 'Repair Installation'. However, if registry keys are heavily corrupted, a complete reinstall using the Cleaner Tool is the only reliable solution.
Are there alternative PDF readers that are less prone to installation errors?
Yes. Lightweight alternatives like the built-in WPS PDF tool in WPS Office offer robust viewing and editing capabilities with a much simpler and more stable update infrastructure.
