Thanks for the details Terry.

"Customize" is there for all the options, though I too keep being surprised by just how quickly it gets going when you click one of the other two buttons.

The uninstall icon is probably not going to come back :( I spent some time trying to come up with an approach that would work, but there seems to be no way to know what the command should be. (That said, I just had an idea where we could install the installer and then include a link to that, which would allow it to be uninstalled... hmm...)

I think the ctypes and distutils test failures are expected right now (especially if you don't also have VS 2015 CTP 6 installed), but the others sound new. Do you have the output logged you could post and I'll create issues for them?
