I followed the directions to install Lean on Windows but perhaps I did something incorrectly? I'm getting the following error: 


20170918 20:40:36 ERROR:: Loader.TryCreatePythonAlgorithm():  System.DllNotFoundException: Unable to load DLL 'python2.7': The specified module could not be found. (Exception from HRESULT: 0x8007007E)


I already checked and python27.dll is present in C:/Windows/System32, and I checked my path variable and C:/Windows/System32 is present there as well. I also followed the direction and deleted the one file in /lib/ and replaced it with the one specifically for Windows. Is there something else I did wrong?
