%11Site Component Manager detected that the %1 service was installed on site system "%2", but Site Component Manager could not deinstall the service.%12

Possible cause: Site Component Manager does not have sufficient access rights to administer the site system.
Solution: Verify that the Site System Installation accounts are properly configured to allow the site to administer the site system.

Site Component Manager uses the %1 service to install Configuration Manager Server Components, and cannot install component %3 until the existing %1 service can be deinstalled. If this problem persists and you cannot fix it, refer to your ConfigMgr Documentation or the Microsoft Knowledge Base for further troubleshooting information.%0
