Hi Stephen,

I had a quick look but can't really tell from your screenshots what the issue is. To hazard a guess, I wonder whether you have created the database before running the installer - which is then trying to create it again but finds one which is already in existence. If that's so, maybe try specifying a new database name and let the Moodle installer create it.

Other than that, I can't tell what the issue might be and would refer you to the Moodle forums and/or your hosting provider / tech support team.

If you want to work locally, there are local (dekstop) installers at the top of this page: https://download.moodle.org/releases/latest/

Hope this helps,
Sven
