Advanced Search hanging

Hi @DPG36656985vtor, 

Sorry for the troubled experience and delayed response.

I'm following up to check if your issue is resolved. For more information, please refer to this help document: https://helpx.adobe.com/acrobat/kb/protected-mode-troubleshooting-reader.html.

Have you tried several files locally and tried running an advanced search? You may also try adding the file location to the privileged location. Launch Acrobat, [ windows user > Edit> Preferences, Mac users: Acrobat >Preferences ] > Categories > Security (Enhanced) - check button "Add Files" or "Add Folder Path." After adding the location path, try re-launching Acrobat. 

If the issue persists, please help us with the following details: 

• A video showing an advanced search for local files vs. files on the file server.
• Acrobat version installed on the machine.
• Operating system name and version.  

Please ensure Acrobat is updated to the latest version. To check for pending updates, launch Acrobat > Help > Check for updates.
