Smart-X has now brought CoreConfigurator back to life. The webpage explains what the tool does and what it looks like. It also explains the licensing: The tool is free for personal use only.
You may use the tool without a valid license or license file for personal and non-commercial use, but you need to purchase a license from Smart-X if you need the tool in a commercial organization. The tool is licensed per organization and a license file can be purchased for $99.
