Help with Python and IPython

Hello,

I was trying to update my Python version yesterday, from 2.3 to 2.7. However, when I had finished installing 2.7, I was unable to open IPython. When I right-click a folder and click "IPython here" a window opened and I was redirected to a command prompt window. I uninstalled all Python after that and tried reinstalling, but had no success in getting IPython working.

If you have any insight into what's going on and how I can remedy the issue, please let me know.
