Call to bcp.exe returns -1073741819

Question

The same snippet of code that calls bcp.exe to create a dat file from a table query works correctly in a simple vb.Net test app but returns error
-1073741819 when the same code is executed in a more complex vb.Net program on the same Win7 Ultimate VMWare session. Making build options the same for both projects has had no effect.
I have been unable to determine why the same call to bcp.exe is successful from the simple test application but not from the more complex application
Windows 7 Ultimate 64 bit
Service Pack 1
Microsoft Visual Studio Ultimate 2012
Version 11.0.60610.01 Update 3
.Net Framework 4.5
Bcp
SQLSvr\SQL_SMO\BCP\x86\SqlCmdLnUtils.msi 
code snippet: 
Public Class Form1
    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim p As Process = New Process
        Dim info As ProcessStartInfo
        Dim exit_code As Integer
        Dim WorkingDirectory As String
        Dim FileName As String
        Dim Output As String
        Dim Argument As String
        exit_code = 0
        WorkingDirectory = "C:\Program Files (x86)\Microsoft SQL Server\110\Tools\Binn"
        FileName = "bcp.exe"
        Argument = "OFS.AmtOFBase.SystemSettings out C:\ProgramData\WebBrix\Archive\SystemSettings.dat -n -Uuser -Ppassword -SServerInstance"
        info = New ProcessStartInfo()
        info.FileName = WorkingDirectory + "\" + FileName
        info.WorkingDirectory = WorkingDirectory
        info.Arguments = Argument
        info.RedirectStandardOutput = True
        info.RedirectStandardError = True
        info.UseShellExecute = False
        info.CreateNoWindow = True
        'info.CreateNoWindow = False
        p.StartInfo = info
        p.Start()
        Output = p.StandardOutput.ReadToEnd() 
        p.WaitForExit()
        If (p.HasExited()) Then
            exit_code = p.ExitCode
        End If
        MessageBox.Show("FileName: " & info.FileName, "ExecuteCommandLine", MessageBoxButtons.OK)
        MessageBox.Show("WorkingDirectory: " & info.WorkingDirectory, "ExecuteCommandLine", MessageBoxButtons.OK)
        MessageBox.Show("Arguments: " & info.Arguments, "ExecuteCommandLine", MessageBoxButtons.OK)
        MessageBox.Show("Output: " & Output, "ExecuteCommandLine", MessageBoxButtons.OK)
        MessageBox.Show("Exit code: " & exit_code.ToString())
        p.Close()
    End Sub
End Class
