"setup/install directory" is just a title, the actual folder is the one in the brackets: "(../setup/)"So yo need to delete the setup folder and the message will disappear ;)rm -rf /var/www/vhosts/domain.com/httpdocs/osticket_help/setup/The "update link the Dashboard" appears only when a database upgrade is necessary. Since the last database upgrade was with version 1.9.4, the only thing that will change with any version above 1.9.4 are the files on the webserver. So when you uploaded the new files (after a backup for sure) and the shows the new version number, everything is done.That said, all you need to do to upgrade from 1.9.6 to 1.9.12 would be to upload the new files. Since I think that is an easy action I'd recommend to this directly and not via Plesk's update link ;)Hope your questions are all answered.Cheers,Michael
