No, they are.

You (or actually your colleague) are not lucky here.
The problem is with MiKTeX, it don't have neccessary file: `mp-tool.mp',
it is part of context package and this package is missing from MiKTeX
repository (it is long standing problem: missing context files in
MiKTeX). If your colleague don't have any objections versus TeX Live,
simply uninstall MiKTeX and install TeX Live (full scheme).

And this is NOT TeXworks problem! Please, post any tex related issues on
texhax mailing list.

And thank you for neat example :).
