Hi,
Do you mean that when you install the tool on a RODC, but it could not installed, and if you are runing the core as a GC, it works?
It seems strange, as this tool is a third party tool, please also post in the partner forum:
http://coreconfig.codeplex.com/
We could try to download the tool and install first then configure the core as RODC. In addition, logon users should have admin right to manage the core.
