Hi Arun,

I can only assume that it was corrupted rather than missing.  If it
was missing, then this is directly caught and relax outputs:

"""
C:\>relax --gui
The dependency 'minfx' has not been installed (see
https://sourceforge.net/projects/minfx/).
C:\>

This is true.

wxpython is not an executable file, so this won't work.  It is a Python module.

The problem is that relax currently does not support the unstable
wxPython-Phoenix versions of wxPython.  I have development branches in
the source code repository dealing with this, but the relax releases
do not.  Specifically because wxPython-Phoenix is not stable and is
changing, and some features used by relax are completely missing (for
now).  You need to use wxPython classic - i.e. versions < 4.0.

Note however that with the upcoming relax 4.1.2 release, I have fixed
the error you see.  There will be significant other issues though if
you continue using wxPython >= 4.0.
