HTTP Error 401.2 when launching Lansweeper Web console

[Georgia1]

I just installed Lansweeper and received: HTTP Error 401.2...

"You are not authorized to view this page...

You do not have permission to view this directory or page using the credentials that you supplied because your Web browser is sending a WWW-authenticate header field that the server is not configured to accept."

I saw an old thread on this but I'm not sure what to do. Lansweeper was installed on same server with Sharepoint 3.0, is this a conflict in IIS?

If possible could you send a screenshot of the error on the webpage with the full url.
Also please post a screenshot about the IIS setup.

This might also help:
