PYPATH No registry key error on installing Gaphor with Python
<p>I have downloaded setup exe from <a href="http://sourceforge.net/projects/gaphor" rel="nofollow">http://sourceforge.net/projects/gaphor</a>. I am already having installation of Python2.7, PyGTK (Complete package). So when I start the install, I deselect Python2.5, PyGtk etc (as I already have python2.7). But as soon as I begin installation, I got the error:</p>

<blockquote>
  <p>PyGtkGUI can't be installed as Python not found on this system. PYPATH = No Registry key found.</p>
</blockquote>

<p>NOTE: 
I am able to proceed, actually i downloaded source code and build it and is working from there. However i would like to know the solution for the original problem reported.</p>
