My system is service pack 1

SELECT 
    SERVERPROPERTY('productversion') as 'Product Version',
    SERVERPROPERTY('productlevel') as 'Service Pack', 
    SERVERPROPERTY('edition') as 'Edition',
    SERVERPROPERTY('instancename') as 'Instance',

The issue is that you are trying to restore a database created in SQL Server 2012, to a SQL Server 2008 instance. This isn't going to work. Instead I suggest using the Copy Database Wizard.

Before you start, ensure that the database has a comparability level of 100.

In the Copy Database wizard, select the 2012 instance as the source.

Select the 2008 instance as the destination.

Select SMO (Server Management Objects) as the transfer method.
