I only have Python 3.4.0 installed. Will you please open a terminal in the
directory with your Python file and run this command:

   python -c 'compile(open("%f").read(),"%f","exec",0,1)'

Let me know what output you get. If that command does not work in the
Windows terminal, then open Textadept's command entry (Ctrl+E) and type
(all on one line): =

Then run the Tools->Compile command and report your output. (Restarting
or resetting Textadept will revert this change you just made; it's not

Thanks a lot.
