Visual studio is giving the error PRJ0019: A tool returned an error code from “Copying DLL…”. The console window includes the output: ‘CopyDLL.cmd’ is not recognized as an internal or external command.
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.
You should check the Custom Build Step (Project Properties->Configuration Properties->Custom Build Step) for all of the projects and all of the files.
It may be easier to open the *.vcproj files in a text editor and check the tags under individual files in the project. Look for any tags that have a non-empty CommandLine attribute.
