Installation problems

Hi!

For some weird reason every install i create, i’m getting:

The file ‘wp-config.php’ already exists. If you need to reset any of the configuration items in this file, please delete it first. You may try installing now.

Have reinstalled it, different subdomain, everything.
I’m just experiencing this, anyone else having this bug?

Weird thing, it does work in an other browser but clearing cache doesn’t fix this.

Regards
