With 3.4.1 and similarly with 3.5.0a0 I get

Testing python 3.4
C:\python34\python.exe: can't open file 'attributeError.py': [Errno 2] No such file or directory
Traceback (most recent call last):
  File "C:\Users\Mark\MyPython\mytest.py", line 34, in <module>
    output = subprocess.check_output("%s %s -output" % (python34loc, myname));
  File "c:\python34\lib\subprocess.py", line 620, in check_output
    raise CalledProcessError(retcode, process.args, output=output)
