Installing pyinstaller via pip leads to “failed to create process”

Question

Does anyone know why pyinstaller immediately fails after installed via pip via anaconda 32bit?

I installed pyinstaller via

Answer 1

"C:\Program Files\Python35-32\python.exe" "C:\Program Files\Python35-32\Scripts\pyinstaller-script.py" --onefile --windowed ex_btn.py

--onefile : create only exe, --windowed : exclude the prompting CMD, ex_btn.py : python script file.

This worked like charm.
