NAV 2016 client crashes

lubost

NAV 2016 client crashes in many functionalities (e.g. change language) with error:
Application: Microsoft.Dynamics.Nav.Client.x86.exe
Framework Version: v4.0.30319
Description: The application requested process termination through System.Environment.FailFast(string message).
Message: Method not found: 'Void System.Runtime.InteropServices.Marshal.StructureToPtr(!!0, IntPtr, Boolean)'.

Running on Windows Server 2008 R2 Enterprise, NAV version 9.0.42815.0.
The same functionalities on Windows Server 2012 Standard (on this computer runs server tier) work fine.

Thanks in advance

Microsoft has fixed lot of crashing errors in CU1.
So please try using CU1 of NAV2016
