Error creating database in SQL Server Management Studio. (Could not load file or assembly 'Microsoft.SqlServer.Sqm)
Close Management Studio.

Find the file Microsoft.SqlServer.Sqm.dll located in one of the following folders:


  C:\Program Files\Microsoft SQL Server\110\Shared\
  C:\Program Files\Microsoft SQL Server\110\Tools\Binn\VSShell\Common7\IDE\
  C:\Program Files (x86)\Microsoft SQL Server\110\Tools\Binn\VSShell\Common7\IDE\


Wherever you find it, make sure it also exists in the other two locations.

I don't know that this will solve your issue, so please let me know - if not I will delete this. This was just too complex to add as a comment.
