It is not necessary to uninstall previous  versions of Python. They
can live happily together. Not only does it work, it's a supported
configuration. That's what the launcher is for.
Mucking with the registry is generally inadvisable. It's too easy to
make a mistake.
If you do decide to uninstall a Python version, do it through the
Control Panel. If that results in problems, submit a bug report.

If I right click o one, I have the option of 'Edit in IDLE'. If I do that, the disk light blinks briefly, and then nothing. So I went into the \python33\lib\idlelib directory and from a CMD window, ran 'python idle.py'. That loads IDLE. but when I ask IDLE to load a file, it navigates to a FileOpen dialog and then closes everything when I actually open the file. I then tried the same thing but used 'pythonw' instead. Same deal.

 I would reinstall Python2.7 and then reinstall Python3.3. That may
straighten out your registry. (It may not)
Let us know if that works.
