If you are getting that error, that's not a fresh install. With "fresh install", meaning an installation on a system where GSX was never installed before.
The error is caused by you having manually edited the Couatl.ini file under %APPDATA%\Virtuali in the previous installation, and made some kind of error, so the file is corrupted/illegal. If you could post that file, I can show you the problem.
ZIP the file and Attach it to a post.
