I have tried all ways of opening IDLE and have uninstalled and reinstalled Python, but when I try to open it it crashes before anything happens

Try to open cmd (win+r -> type 'cmd' -> press enter), cd in the Python directory and do "python.exe Lib\idlelib\idle.py".
If that doesn't work it should give you a traceback.  Once you get the traceback copy/paste it here, so we can figure out what's going on.

IDLE with Py3.2.2 works fine on Win 7 for me (desktop) and daughter (laptop), so there is something peculiar with your system.

That is the traceback given when I run idle.py through windows command prompt

Are you using the .msi installer from python.org?
Or one from activestate or enthought?

Are you using some "unusual" keyboard layout?

This issue is very similar to issue5707: it is possible to define a custom key binding to "<Alt>" or "<Control>": just click the Alt box and don't select a letter.
There is no check, it's possible to save this buggy key binding, and IDLE won't start anymore.

IDLE should:
- check the validity of the binding and refuse to save it when it is invalid
- gracefully skip invalid bindings from the config file

What did you do to solve the problem?

msg144845 - (view) Author: Terry J. Reedy (terry.reedy) * Date: 2011-10-03 22:15

While this issue and #4765 are about the same effect, with a similar workaround, Amaury has indentified a separate bug in the custom key mechanism. So I retitled it to refer to that bug.
