You're all set
RomansCode is installed and running on this site. There is nothing more for the installer to do.

Tidy up (recommended)
For security, delete the entire /install/ directory from your server now. The installer has locked itself, but removing the folder eliminates the attack surface entirely. You can always re-upload it if you ever need to reinstall.
