We did not change the python detection code since
alpha-1... :-(<br>

<div>However, this must be the cause of the
problems. I just tried adding Python to the PATH
environment variable, and everything worked
perfectly. <br>

<div>Maybe LyX is tricked in some way by the
python.exe that Microsoft puts in the PATH? (It's
not a real Python, just something that tells you
how to install it.) With this, you can start "a
Python executable", but it will not execute any
script (I believe it always returns an error
code).<br>

<p>That may be. Where do we record what Python we found?<br>
</p>
<p>If so, then the solution would be to try running some
simple Python file using whatever we find and see if
that works. E.g. run the program "1;".</p>

<div>I have contributed some lines to python recognition on
windows (<a href="https://www.lyx.org/trac/ticket/11712"
moz-do-not-send="true">https://www.lyx.org/trac/ticket/11712</a>):
But because of what was written by Thibaut (adding Python to
PATH), it looks to me that the failure is not in this
function but in rather LyX failing to add path prefix. I can
also reproduce this btw. I have checked the path prefix in
the settings, all is done right there. But even if I add
python dir to PATH, it then will not find other dependencies
(imagemagik and ghostscript).<br clear="all">

<p>I would try reverting all the changes to configure.py since alpha
1 and see if that fixes the problem. We did not get this report
with alpha 1. These are:</p>

<p>If that helps, then add them back one at a time and find the
culprit.<br>
