Just this morning, I installed SQL Server 2008 Express SP2 from the Web Platform Installer. When I went to restore some databases, the error message was that my database files are from version 10.5 and I have version 10.0.4000. I tried downloading this file from Microsoft, but it errored out saying that I don't have anything to upgrade in my machine.
I ran this code:
SELECT
SERVERPROPERTY('productversion') as 'Product Version',
SERVERPROPERTY('productlevel') as 'Service Pack',
SERVERPROPERTY('edition') as 'Edition',
SERVERPROPERTY('instancename') as 'Instance',
SERVERPROPERTY('servername') as 'Server Name'
And got back this:
10.0.4000.0 SP2 Express Edition SQLEXPRESS DEV-PC1\SQLEXPRESS
