On Windows 7 SP1 x64 after having installed Python 3.3 (x64) in “c:\Python33” and then subsequently installing Python 3.4 (x64) in “c:\Python34”, and then uninstalling the Python 3.3 (x64) and I’m not sure what else I may have done, I can no longer do any of the following:
	Open an IDLE window using the Windows Start Menu;
	Uninstall, Change, or Repair Python 3.4 using Windows Programs and Features;
	Uninstall Python 3.4 using Windows Start Menu;
	Reinstall Python 3.4 using the current 3.4 .msi install program.

I would like to go back to being able to do a forced fresh install.

I am a Python newby so maybe I should open a new incident but I don’t know how to start one yet.

Perhaps I should try the previously described reproduce procedure by doing the following:
Rename or delete target installation folder and then rerun Python installation procedure to install.
