[Python-Dev] Can't install Python 3.5rc3

2015-09-07 Thread MRAB
I've been unable to install Python 3.5rc3. It progresses to installing Tcl/tk, then reports that a newer version of 3.5 is already installed, then it rolls back (slowly). I don't know where it's finding this "newer version"; I've uninstalled the previous releases of Python 3.5. I'm on Windows 1
