Missing Python.Runtime in new pre-release version of Python.net #34
Description
Hi!
I have installed (using pip) the new prerelease version of Python.net. If I run python.exe, and do 'import cld' I get a FileLoadException, as shown below:

My best guess is that you have some other versions of either clr.pyd or Python.Runtime.dll hanging around in your python installation that do not come from the pip install but from some manual build you did at some other point in time, and that this is messing things up. Can you please try the following: 1) uninstall the version you got via pip ("pip uninstall pythonnet"), 2) search for any remains of a previous attempt to install this in your python directory and all its sub-directories. You should be looking for clr.pyd and Python.Runtime.dll mainly. If there are any copies left anywhere, get rid of them to make sure that when you do import clr later, you are not loading one of these copies. 3) install the pre-release of python.net again via the pip command you already used.
