xcopy is not recognized as an internal or external command, operable program or batch file

Question

I have a problem using \'xcopy\' command.

I\'m building a C# project with msbuild. At the end of the build, a batch file is called to copy my assemblies from Debug/R

Answer 1

I encountered the same problem.

It seems to be a problem with the path environment variable within Visual Studio.

When I added a "path" statement to the beginning of my build event, it produced the following output:

PATH=

This seems to indicate that the path is empty within the VS build environment.

When I specify the full path to xcopy like this, the problem went away:

%systemroot%\System32\xcopy ...

I'm not sure what caused Visual Studio to lose it's path.
