The following is showing in my admin panel:

Zenphoto has detected a change in your installation.
Your database software has changed from MySQLi 5.6.23 to MySQLi 5.6.33.
The change detected may not be critical but you should run setup at your earliest convenience.

When I try to run the setup, which does exist, I get the following message:

Warning: chdir(): No such file or directory (errno 2) in /home/otsegodance/public_html/events/zp-core/setup.php on line 26
You must restore the setup files from the 1.4.10 [3d5be820ca] release.

On Admin > Overview you should see a button called
"Setup » restore scripts".
After you have clicked this button you should be able to run setup.
