There were some pretty big changes on the Windows side of things for Python 3.5.0 - not just porting the installer to the Wix toolset and migrating to a new of Visual Studio, but also adjusting to some fairly major underlying changes to the way the Microsoft C runtime works in general. As part of all that, I believe we also finally switched to being a well behaved Windows citizen and now default to installing into Program Files rather than the root of C:\. With the wide variety of system configurations out there, that degree of change from past practices was always going to encounter some teething troubles. Fortunately, we're unlikely to ever have to go through a shift like this again, and are now in a situation where our installation practices not only better align with Microsoft's recommendations, but are able to benefit from future evolution in the Wix toolset rather than necessarily having to track changes to Microsoft's recommendations directly. Cheers, Nick.
