Update and Repair Adobe Acrobat Installation
Updating the software to the latest patch or running the built-in repair tool often resolves slow loading and spinning wheel bugs.
Software bugs or corrupted installation files can frequently cause specific tools to lag. Adobe regularly releases patches to fix performance issues.
Open Adobe Acrobat, click on the 'Help' menu at the top, and select 'Check for Updates'. Install any available updates and restart your computer to apply the changes.
If the issue persists after updating, open Acrobat again, go to the 'Help' menu, and click 'Repair Installation'. Follow the on-screen prompts and restart your PC once the process completes.
