AD RMS setup cannot continue because it failed to create the {1} database. The following error was provided from SQL Server: {0}. This error can be caused if a database file with the same name already exists on the database server, which can happen if you are reinstalling AD RMS on this computer. If this is the case, see http://go.microsoft.com/fwlink/?LinkId=131091 for help in resolving the problem. Otherwise, verify that you have appropriate permissions on the SQL Server, and then retry running AD RMS setup.
