I can't install the CiviCRM onto my Joomla. When trying to install it looks like it's working then it goes back to the install screen and nothing is installed. I have tried the zip file and tmp folder.
Make sure you are running the update database action, but it sounds like you might be installing a bad package or timing out. Could you share a screenshot? I might not be able to help much tonight, but I'd be happy to help you later this week if you don't have it resolved by then.
