My Windows version is Windows 8 pro, 64 bit Should I install http://www.python.org/ftp/python/2.7.4/python-2.7.4.msi
or http://www.python.org/ftp/python/2.7.4/python-2.7.4.amd64.msi to make compatible with Lyx? nicola From: Alex Fernandez Sent: Thursday, May 9, 2013 4:58 PM To: Nicola Scafetta, Ph. D.

A windows opens and says: "Lyx cannot convert file. An error occurred while running." If the line that Alex Vergara suggested does not work, it looks like Python is not properly installed on your system. I would suggest reinstalling Python from scratch: http://www.python.org/download/releases/2.7.4/ Pick the release for your version of Windows and install it, then try again. Alex.
