******************************
If you know you don't have Python, the package author has an alternative 
'bundled' version you can get from:
https://github.com/cbm755/octsympy/releases

The file you would want is symbolic-win-py-bundle-2.2.1.zip

symbolic-win-py-bundle-x.x.x.zip

includes both python and sympi.

******************************

For Nick J,
>>pkg install -auto symbolic-win-py-bundle-2.2.2.zip

seems to work flawlessly.

But for my PC (win 7 64; perhaps windows version itself is irrelevant),
the above does not work.

As I wrote
http://octave.1599824.n4.nabble.com/Symbolic-package-for-Octave-tp4670576p4671655.html


If I install python and sympy externally and set appropriate PATH and
I install symbolic package in usual way (pkg install -forge symbolic),
the symbolic package works without problem.

I do not know why I and the the person who made the original post failed 
by Nick J instruction while Nick seemed not to have problem with 
symbolic-win-py-bundle-2.2.2.zip
