Originally created issue:

Copied text below:

I had already Python 3 installed with the environment variable PYTHONHOME=C:\Program Files\Python35. I attempted to install Python 2, but received this issue (although I was installing python 2 after having installed 3):

After multiple attempts, I was able to successfully install Python 2 by doing either of following:

* Removing the pip feature from Python 2 installation
* Removing my PYTHONHOME environment variable and running a complete Python 2 installation

Although I resolved my issue, I would like to file this as a bug if it hasn't been filed already.

Thanks for the write up. This has already been resolved for 2.7.13 (where install will complete but pip won't be available), and as you discovered you should never set PYTHONHOME (or PYTHONPATH) globally, since it will affect every version and not just the one you intended.
