3.3.15 Update issue

[mrix2000]

Hello all, I downloaded the full package to update with as I would normally do but after install I get this error below

Fatal error: Composer dependencies have not been set up yet, run 'php ../composer.phar install' from the phpBB directory to do so. in /home/mrixadve/public_html/includes/startup.php on line 80

Any idea`s greatly appreciated

Hello all, just a update that I noticed the php version was set on 7.4 so I updated to the later version of php 8.3 and the forum is working as normal
