Win_ros installation 'python _partent_package_path.py' is not recognized as an internal or external command?

[randylewis7]

Hello, yesterday I followed the win_ros installation instructions here:
http://wiki.ros.org/win_ros/hydro/Msvc%20SDK

After some problems with setting PATH variables, I got the demo/test talker/listener program to run in conjunction with roscore. However, today, after attempting to follow this tutorial:

http://wiki.ros.org/win_ros/hydro/Msvc%20SDK%20Projects

to be able to actually create my own nodes and stuff, I have somehow messed something up, because running the line

call C:\opt\ros\hydro\x86\setup.bat now produces the error:

' 'is not recognized as an internal or external command ... etc. 'python _parent_package_path.py' is not recognized ... etc.

Any idea what I screwed up, or how to fix it?

Thanks
