Hi Arya,
That looks like a problem with the version of Python you were trying to
use. I don't think ParaViewWeb supports Python versions lower than 2.7, so
you could check the version you were using before you switched to the
binary. Maybe you were trying to use Python 2.6 or lower? At any rate,
I'm glad you finally got it working.
Cheers,
Scott
