C# Run CMD from website button

I play Terraria. I host games sometimes. I want users to be able to grab a current map of my world, whenever they want to. So I created a simple web page to use MoreTerra (a mapping software) to create a map in the background for me and a web page to display the map to users.

MoreTerra comes with a batch file that runs itself from the command line. the batchfile contains the following:

@ECHO OFF
cmd.exe /c MoreTerra.exe %1 %2 %3 %4
@ECHO ON

I want to execute this when a user clicks a button on my web page, so I created the following code:

try
           {
               // declare variables
               string worldFile = "\"" + AppSettings.GetAppSetting("WorldFile", false) + "\"";
               string outputLocation = "\"" + AppSettings.GetAppSetting("OutputLocation", false) + @"\" + AppSettings.GetAppSetting("ImageFileName", false) + "\"";
               string fileName = AppSettings.GetAppSetting("MT_Location", false) + @"\" + "MoreTerraNoGui.bat";
               ProcessStartInfo si = new ProcessStartInfo();
               // define StartInfo
               si.FileName = @"C:\Windows\SysWOW64\cmd.exe";
               si.Arguments = "/c " + fileName + " -w " + worldFile + " -o " + outputLocation;
               si.WorkingDirectory = AppSettings.GetAppSetting("MT_Location", false);
               si.CreateNoWindow = true;
               si.WindowStyle = ProcessWindowStyle.Hidden;
               si.UseShellExecute = false;
               si.RedirectStandardOutput = true;
               si.RedirectStandardError = true;
               // log arguments for debug check
               Log.WriteToLog(ProjectLogType, "btnRefresh_Click", si.Arguments, LogEnum.Debug);
               // start process and wait for it to finish
               Process subProcess = Process.Start(si);
               subProcess.WaitForExit();
               // log output and errors
               string output = subProcess.StandardOutput.ReadToEnd();
               string error = subProcess.StandardError.ReadToEnd();
               Log.WriteToLog(ProjectLogType, "btnRefresh_Click", output, LogEnum.Debug);
               Log.WriteToLog(ProjectLogType, "btnRefresh_Click", error, LogEnum.Debug);
           }
           catch(Exception x)
           {
               Log.WriteToLog(ProjectLogType, "btnRefresh_Click", x, LogEnum.Critical);
           }

So far it hasn't really done anything. In the Task Manager, I can see Console Window Host process start and stop in less than a second every time I click the button, but no image is generated. The Output and Error variables are always empty. but when I debug and break at "subProcess.WaitForExit();" I can see this error in the Locals Window in Visual Studio

-       MainModule  'subProcess.MainModule' threw an exception of type 'System.ComponentModel.Win32Exception'   System.Diagnostics.ProcessModule {System.ComponentModel.Win32Exception}
+       base    {"A 32 bit processes cannot access modules of a 64 bit process."}   System.Runtime.InteropServices.ExternalException {System.ComponentModel.Win32Exception}
        NativeErrorCode 299 int

I've tried using the same cmd.exe in both the C# code and in the batch file, both x86, and x64, but to no avail.
I used corflags.exe to check MoreTerra.exe, and it's not 32bit required, my code is compiled for AnyCPU, so I'm at a real loss.
I've been scouring the internet, but everything I've found is incorporated into the above code.

Any help would be greatly appreciated. TIA
