When installing SP2013 I got this error:
Failed to create the configuration database
An exception of type Microsoft.Sharepoint.SPException was thrown. Additional exception information: The language is not supported on the server.
I tried to doing this: http://support.microsoft.com/kb/2002277 I don't have a directory 12, so I did it in 14 and 15 instead.
This was suggested on some other forums as well. Still didn't fix my problem.
Any ideas how to fix this?
