Adobe Acrobat Reader DC not responding.

Hi Aland82523103,

When exactly you are getting the message "Adobe Acrobat Reader DC not responding" ?

Is it during launch of the application or when you try to open any pdf or search in the pdf file?

Also, what is the operating system that you have?

Check for the update if any available under Help>Check for update (update the application)

If it still doesn't work then you need to reset the preferences of Adobe Reader DC.

For Windows-

• Quit Reader.
• In Windows Explorer, go to the Preferences folder:  

    (Windows 7 or higher) C:\Users\[username]\AppData\Roaming\Adobe\Acrobat\[version]

     Or %Appdata%>Roaming>Adobe>Acrobat>[version]

• Move the Preferences folder to another location (for example, C:\Temp).
• Restart Reader.

For Mac-

• Quit Reader.
• Drag the following files from the Users/[Username]/Library/Preferences folder to the Desktop:

Acrobat WebCapture Cookies

com.adobe.Acrobat.Pro.plist or com.adobe.Acrobat.Pro_x86_9.0.plist

• Acrobat Distiller Prefs and com.adobe.Acrobat.Pro.plist (if you are troubleshooting an issue with Distiller)
• The Acrobat folder, which contains preferences for forms (MRUFormsList), collaboration (OfflineDocs), and color settings (AcrobatColor Settings.csf)
• Restart Reader.

Let us know if it still doesn't work.

Regards,

Akanchha
