Cannot Configure the Administration Database
When configuring Commerce Server 2009 R2 by using the Commerce Server Configuration Wizard, the Administration database (MSCS_Admin) configuration screen displays an error message starting with "Execution of the TSQL command," and you cannot continue.
To resolve this issue, do the following:
Verify that the SQL Server agent service is running on the computer that is running SQL Server.
If you are starting a new installation of Commerce Server 2009 R2, and you have used SQL Server Management Studio to verify that no MSCS_Admin or DirectMailer database exists on the server that is running SQL Server, verify that the SQL Server Data folder does not contain the following files:
Mscs_admin.mdf
Mscs_admin.ldf
Directmailer.mdf
Directmailer.ldf
Verify that you have purchased enough licenses for your SQL Server installations.
Verify that you are not using a pre-release version of SQL Server.
