[Tutor] Problems installing

[Evert Rol]

> I just downloaded Python 2.6.5 onto my windows vista laptop. I am attempting to install "escript version 3: Solution of Partial Differential Equations (PDE) using Finite Elements (FEM)." I downloaded the files and manually placed them in their appropriately place on my computer according to the ReadMe file. However, when I try to import escript, I get an error:
> 
> I know nothing about escript, but according to the install doc on https://launchpad.net/escript-finley/, it requires python 2.5.4.  The distribution appears to consist entirely of .pyc files, so I think you need to install the version of python that it requires.

There is a source distribution that has the *.py files, but looking at the dependencies, that's not going to be easy to install.
Then again, the webpage claims the third party software includes Python. So your system picks up Python 2.6 (which is the default), but escript does actually include Python, presumably 2.5. So somehow, you'll need to setup your system that it picks up the correct Python. Or rather, find that Python in the escript installation (I have no idea how it's installed, so can't tell you where to look), and use that Python instead when import escript.

What files did you download? Since you said you manually installed them in the correct places; that could/should have included Python.
