Please download from your server files:
<EPESI DIR>/include.php
<EPESI DIR>/include/module_install.php
<EPESI DIR>/modules/Utils/Tree/TreeInstall.php
and paste them here in the zip file as an attachment.
Your installation is partially done. You've got some files in the data dir, the database exists, and a lot of modules is installed. Could you please check your http server logs?
It's strange, because it looks like you've got data/config.php file, but your server redirects me (because of 404) to your global page instead of show "Direct access forbidden".
Regards,
Adam
