The Roxen CMS installer is an integrated thing, which bugs-out at this problem.I guess you're best off just deleting that line. But it's not clear why it fails. Since you said that Roxen works without the environment file then the mysql driver can't be the problem.
I can't restart it, because it deletes the installation files.As I restart the main installer, it re-copies the broken environment file. i.e. full-circle.
