python 2.7 - PyInstaller not working on simple HelloWorld Program

Question

So I am running on 64-bit Windows 7, and I set up Pyinstaller with Pip and PyWin32. I have python 2.7.

I made a simple hello world Program with this code

print "hello world!"

I put the file in the same directory as PyInstaller, and ran this code in the command prompt

pyinstaller.py helloWorld.py

Yet, when I try that, I get this error message:

Error loading Python DLL: C:PROGRA~1PYINST~1.1uildHELLOW~1python27.dll (error code 126)

What am I doing wrong and how do I fix this?

Answer 1

Run with the -F flag to produce the standalone exe:

pyinstaller -F helloworld.py

It will output to dist/helloworld.exe

NOTE this is a different location to when -F is not used, be sure to run the right exe afterwards.
