I want to access the Microsfot dyamic global variables in my .Net Project So I written code like this
          
 try
            {
                string UserName = Microsoft.Dexterity.Applications.Dynamics.Globals.UserName.Value.ToString();

           }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }

But I am getting error : the specified module could not be found. (Exception from HRESULT: 0x8007007E)

I have installed VSToolsInstallRuntime, VSToolsInstallSDK and also I added all reference

using Microsoft.Dexterity.Applications;
using Microsoft.Dexterity.Applications.DynamicsDictionary
