How to add Python to Windows registry

Question

I've downloaded Enthought Canopy EPD Free (now Canopy Express) from https://www.enthought.com/products/epd/free/ and want to install SciKit Learn (http://sourceforge.net/projects/scikit-learn/files/) which is not part of the basic EPD Free install.

When trying to install it does not find Python in the Windows registry. How do I adjust the registry so that it recognizes the Enthought version of Python?

Answer 1

I faced to the same problem. I solved it by

1. navigate to HKEY_CURRENT_USERSoftwarePythonPythonCore3.4InstallPath and edit the default key with the output of C:> where python.exe command.
2. navigate to HKEY_CURRENT_USERSoftwarePythonPythonCore3.4InstallPathInstallGroup and edit the default key with Python 3.4

Note: My python version is 3.4 and you need to replace 3.4 with your python version.

Normally you can find Registry entries for Python in HKEY_LOCAL_MACHINESOFTWAREPythonPythonCore<version>. You just need to copy those entries to HKEY_CURRENT_USERSoftwarePythonPythonCore<version>
