Meridian Administrator empty and unresponsive

By default, Meridian Enterprise Administrator relies on SQL Server Compact Edition being installed on 64-bit computers to store the user accounts database. If it is not installed or the ConnectionString registry setting is not set correctly, the Meridian Administrator window will be empty and unresponsive when it is launched. To resolve this, either install SQL Server Compact Edition or set the ConnectionString registry setting. For more information about installing SQL Server Compact Edition or the ConnectionString registry setting, see BlueCielo Meridian Enterprise Administrator's Guide.
