Hi,
Try quitting all the adobe processes from Activity monitor.
Trash the following folders :
1- Go To: Finder > Applications > Utilities > Adobe Installer > Uninstall Adobe Acrobat
2-Right click on Finder icon and select "Go-To" Folder option. -- You will get a text box, type-in below command and then hit 'Return' key.( " Do not miss ~ symbol " )
~/library ( It will open User Library folder. )
3- Then navigate to Application Support>Adobe> trash Acrobat
4- Again > Right click on Finder icon and select "Go-To" Folder option.> You will get a text box, type-in below command and then hit 'Return' key./library ( It will open System Library folder.)
5- Then navigate to Application Support>Adobe> trash Acrobat
6- Run the acrobat cleaner tool : http://download.macromedia.com/SupportTools/Cleaner/mac/AdobeCreativeCloudCleanerTool.dmg
Download the program again from : Download Acrobat products | Standard, Pro | DC, XI, X
