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?

Once you've located the registry key you want to add to, you can add the key or value you want to add: If you're creating a new registry key, right-click or tap-and-hold on the key it should exist under and choose New > Key. Name the new registry key and then press Enter.
We need to import the module named winreg into the python environment. In the below example we use the winreg module to first connect to the registry using the ConnectRegistry function and then access the registry using OpenKey function. Finally we design a for loop to print the result of the keys accessed.
Open regedit, navigate to HKEY_CURRENT_USER\SOFTWARE\Python\PythonCore\<version>\PythonPath and add or edit the default key with this the value found in the first command. Logout, login and python should be found.
I faced to the same problem. I solved it by
HKEY_CURRENT_USER\Software\Python\PythonCore\3.4\InstallPath and edit the default key with the output of C:\> where python.exe command.HKEY_CURRENT_USER\Software\Python\PythonCore\3.4\InstallPath\InstallGroup 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_MACHINE\SOFTWARE\Python\PythonCore\<version>. You just need to copy those entries to HKEY_CURRENT_USER\Software\Python\PythonCore\<version>

You can find the Python executable with this command:
C:\> where python.exe It should return something like:
C:\Users\<user>\AppData\Local\enthought\Canopy32\User\python.exe Open regedit, navigate to HKEY_CURRENT_USER\SOFTWARE\Python\PythonCore\<version>\PythonPath and add or edit the default key with this the value found in the first command. Logout, login and python should be found. SciKit can now be installed.
