Hello everyone,

I've just downloaded the Vision Egg software with source code and demos,

That being said, I've already encountered a problem running the demos. 
I've gone through the step-by-step Windows installation guide (I'm running

check-config.py also confirms that everything is OK, with the exception of 
the optional modules Pyro and winioport which failed.

Going to the demo directory from the command prompt and trying to run the 
demos, results in the following:

Any idea on what's going on or suggestions?

I'm running Windows XP.  The version of everything I installed is the 
version that is directly linked from the Windows Install page:

Thanks for the help!

Hmm, looking at the output of check-config.py again, it has listed:


which doesn't exist; everything has been installed to the C: directory. 
Might this have something to do with the problem?  If so, how do I change
