I am having this same problem in a new Amazon instance of Server 10.1 SP1.
The default SQL Express instance in this AMI is called "MSSQLSERVER" instead of "SQLEXPRESS."
So, when I browse to 'HKEY_LOCAL_MACHINE', 'SYSTEM\CurrentControlSet\Services\' there is no MSSQL$sqlexpress. Instead, there is a 'MSSQLSERVER' - and there is already an "ArcSDE_License" key there.
I tried the suggested workaround of generating the license information from the link provided, using a valid ECP number, then creating the "ArcSDE_License" key (I renamed the old one) and entering the info.
I still get the same error.
Is ArcGIS Desktop looking specifically for a "SQLEXPRESS" instance name and registry key?
