The Certificate Enrollment Web Service could not be installed because an incompatible configuration was selected. To resolve this issue, remove the Certificate Enrollment Web Service. If you want to use key based renewal, enable both client certificate authentication and renewal-only mode. If you want to use user name and password authentication or Windows authentication, disable key based renewal, and then run Setup again.
