Gallery - Joomla 3

Dear Balbooa-Support-Team,

i have a client who still runs an old Joomla 3 website. Yesterday, I made a few updates to the website, and I can't perform an automatic update for the gallery. I get a message saying I have to do it manually. When I log in to your site, I can't find a version available for download that still runs under Joomla 3. Can you help me? I've attached a screenshot.

Thank you very much.
