[python-win32] pyinstaller: failed to create process

[Ulli Horlacher]

I have to compile my Python scripts into standalone Windows executables
which I can give to Windows users without Python.
I use PyInstaller on Windows 7 for this task.
It runs without problems with Python 2.7.10
But I am not able to get it working with Python 3.5

First, I was not able to install PyInstaller at all. I got

C:\Users\admin>pip install pypiwin32
   
Collecting pypiwin32
  Downloading pypiwin32-219-cp35-none-win32.whl (7.9MB)
    100% |################################| 7.9MB 61kB/s
Installing collected packages: pypiwin32
Exception:
(...)
  File "c:\program files (x86)\python 3.5\lib\shutil.py", line 115, in copyfile 
    with open(dst, 'wb') as fdst:
PermissionError: [Errno 13] Permission denied: 'c:\\program files (x86)\\python3.5\\Lib\\site-packages\\PyWin32.chm'

I found, I have to deactivate Windows UAC with:
   
C:\Windows\System32\UserAccountControlSettings.exe

Then I was able to run

pip install pypiwin32
pip install pyinstaller

without errors.

BUT pyinstaller does not work:

S:\python>pyinstaller.exe --onefile tk.py
failed to create process.

S:\python>pyinstaller --version
failed to create process.


What is wrong?
