Python 2.7 to EXE - can't install pyinstaller

Question

I'm using Win10 and have some code written in Python 2.7 (have to be, it's not mine) and I want to create an EXE file. I want to install pyinstaller but can't do it. I've already tried to update the pip version, the suteuptools, to install "ez_setup" to download the file from the pyinstaller website but it doesn't help.

These are the ways I tried to download it:

pip install pyinstaller
pip install https://github.com/pyinstaller/pyinstaller/archive/develop.tar.gz
easy_install pyinstaller

And these are the errors I received:

    C:\Users\roy.a\Desktop\work\EMV IL - cryptera\cryptera 
    Python\scripts\Activation python>easy_install pyinstaller
    WARNING: The easy_install command is deprecated and will be removed

Any help will be appreciated Thanks

The changelog for PyInstaller documents that Python 2.7 has been dropped so you will have to install an older version that has compatibility with 2.7.

Try to install an older version using pip install pyinstaller==3.6.

You will likely have to do similar for other third-party modules that you require.
