Pyinstaller 3.4 Not Working on Windows 10 with Python 2.7

I have recently reinstalled Windows 10. I am using Python 2.7 and trying to make a small executable using Pyinstaller 3.4. and I get the following error:

Does anyone know what is going on? It worked fine with the same file before reinstalling everything.

I ended up just downgrading Pyinstaller to 3.3 and that worked fine for my application.

pip install pyinstaller==3.3

Note: 3.0 also works as stated in my comment. I successfully tried 3.3 and am now using it because its newer.

As per Mike's own input, installing PyInstaller 3.0 will fix the problem. Just tried on Win7 Enterprise and it works just fine.
