In windows 7, Add/Remove is not Programs and Features. Looking there, I 
found an entry for .0b2 that should have been removed by the .0b3 
install, but was not. When I tried to uninstall .0b2, I got the same box 
about not being able to run something. I downloaded the .0b2 installer 
from www.python.org/ftp/python/3.4.0/, repaired the .0b2 installation, 
and then uninstalled it, and the entry disappeared. I was then able to 
install 64bit .0c1. So I conclude that a glitch in the .0b3 
installation, leaving a bit of .0b2, made .0c1 unable to uninstall .0b3
