Adding the License Key
Initial License Key Configuration
Adding the license key (if you didn’t do it during setup or are renewing)
We need to add the trial or full version license key to Callisto.
Open IIS Admin, browse to the Callisto website and open Application Settings.

Edit the CallistoLicenseKey value and paste in the license key provided to you.
(Callisto is installed to port 80 by default, you can change this in the installer and later with IIS Admin if you wish.)
Browse to the server, (default is http://localhost) the login page is displayed, log in with "admin", the initial password is “123qwe”
Set a new password when prompted and log back in.
