New Post: Unable to use latest R 1.5.16.30632 in VS2013 Win 8.1 x64 .NET 4.0 => x64, WinForms project

R installed using NuGet in VS 2013 without error. RDotNet and RDotNet.NativeLibrary 1.5.16.30632 references added to project as expected.

ErrorL "An unhandled exception of type 'System.ApplicationException' occurred in RDotNet.NativeLibrary.dll Additional information: Windows Registry key 'SOFTWARE\R-core' not found in HKEY_LOCAL_MACHINE nor HKEY_CURRENT_USER"

using RDotNet;

// crashes on first line:

        REngine.SetEnvironmentVariables();
        engine = REngine.GetInstance();
        if (engine.IsRunning == false)
        {
            engine.Initialize();
        }

My research on StackOverFlow and here has turned up no solution, but it is obvious this is a frequent problem.

thanks, Bill
