[Mono-list] g_spawn_command_line_async

[Aaron Bockover]

I'm not familiar with Windows, but I'm guessing that %ProgramFiles% is
an environment variable, and it is probably not set when you make the
call. It probably works on the command line in windows, because when you
run the terminal, it probably sets that variable.

When I was doing some process control in C under GLib on Linux, I
remember reading that environment variables were not set, or there was
something specific you had to do.

See:
