Issue installing GWM

I have recently downloaded the trial version of the SAP Gateway for Microsoft and have been unsuccessful with getting it installed on my workstation. I get the following error immediately after executing the MSI. I am using Visual Studion 2013 on a Win2008R2 workstation.  Any idea how to overcome this little set back?

      Hi John,

      can you take a look at

      There are a few prerequisites with the new service pack 04 because of our integration with Microsoft Azure. Please make sure that you have the following files installed upfront:


      The following Dynamic Link Library files (with the extension .dll) should be present in the Global Assembly Cache (GAC) folder for installation: 

      •   Newtonsoft.Json.dll (version 5.0.6)
      •   Microsoft.IdentityModel.Clients.ActiveDirectory.dll (version 1.0.2)
      •   Microsoft.IdentityModel.Clients.ActiveDirectory.WindowsForms.dll (version 1.0.2)  Newtonsoft.Json.dll is available in the Json.Net 5.0.6 package,Microsoft.IdentityModel.Clients.ActiveDirectory.dll andMicrosoft.IdentityModel.Clients.ActiveDirectory.WindowsForms.dll are available in the Active Directory Authentication Library 1.0.2 package. These packages can be downloaded at published on non-SAP sitewith a registered account. The downloaded files can be extracted to view the DLL files in the lib folder based on the .NET Framework version. Follow these steps to add the required DLL files to the GAC folder: 
        1. Open Visual Studio Tools on the Start menu, right-click on Developer Command Prompt for VS2013 or Developer Command Prompt for VS2010 (depending on the version of Visual Studio being used) and choose Run as Administrator, choose Yes if Windows displays a security prompt.
        2. In Developer Command Prompt, run the command gacutil -if <file path of DLL> and press Enter. Repeat this step till all the required DLL files are added successfully.
