title: error PRJ0019: A tool returned an error code from "Copying DLL..."
body: <p>Visual studio is giving the error <strong>PRJ0019: A tool returned an error code from "Copying DLL...".</strong> The console window includes the output: 'CopyDLL.cmd' is not recognized as an internal or external command.</p>
  
  <p>Here is some background as to why I don't know about the tool which is copying. Someone left the company a year ago and forgot to check in their latest version of code for a MS Visual Studio 2008 project using C# and C+_. Now we need to fix the program, but can't find the code and I've been assigned with trying to clean the mess up.</p>
