calling executable from Python Win32 IDLE works but the same from Windows console Python session doesn't

Question

I am trying to run an executable file from Python using os.system or subprocess, in my Windows machine, but I have a strange problem.

The os.system/subprocess call works fine with: 32-bit Python console from IDLE,

but but it doesn't work from: 1) The cmd if I run any Python session (32 or 64) 2) If I use any Python version from Spyder. 3) PyCharm with any Python version;

and I get these errors:

1. Run time error

2. An error window that appears immediately after I click OK on the first

I've spent many hours on this, but I am unable to figure out why this happens. Why wont subprocess or os.system work the same from difference Python consoles?

Answer 1

you may perhaps retry after using "script\\make_winpython_fix.bat", but winpython-2.7.9.5 didn't have that option, (that came october 8th 2015)
