MDS 2014 - Could not load file or assembly Microsoft.SQLServer.Instapi error

Hello,

I have just install MDS 2014 web application on different server then SQL server 2014 and MDS database. 

When I connect to MDS as MDS/Administrator I get message “Could not load file or assembly ‘Microsoft.SQLServer.Instapi, Version= 12.0.0.0….”  
When I try to connect as another user I get „Access is denied”  error.
