Hi,
I have installed SQL Server 2012 Express edition (name of installation media: en_sql_server_2012_express_edition_with_advanced_services_x64.exe) from MSDN and I have installed the application on my pc with Windows 7 Exterprise.
Everything is working fine except when I am trying to create "New Database Diagram", where I recieve following error message:

TITLE: Microsoft SQL Server Management Studio ------------------------------
Attempted to read or write protected memory. This is often an indication that other memory is corrupt. (Microsoft.VisualStudio.OLE.Interop)
------------------------------ BUTTONS:
OK ------------------------------

I have tried two times to reinstall SQL Server 2012 Express, and I have every time recieved the same problem.
How can I solve the problem?
