Symptoms

I can't access to the K2 Designer.
If I comment the line with the NTLM provider, I get this other error:
Server Error:

No se puede cargar el archivo o ensamblado 'SourceCode.Forms.Controls.Web.ManagementControlPack' ni una de sus dependencias. El sistema no puede encontrar el archivo especificado.

Diagnoses

The error on designer translated is:
Could not load file or assembly 'SourceCode.Forms.Controls.Web.ManagementControlPack' or one of its dependencies.


 

Resolution

Installing K2 BlackPearl fixed this issue.
