How do I access IDLE in Win7

[W. eWatson]

In the mean time, I punted and re-installed. It's still not quite right. 
I uninstalled it. I was asked during install if I wanted to remove 
c:\Python25. It was still there and had several folders (Lib, Scripts) 
and files (fishe.py, RemovePIL.exe, junk.py). I said yes. It installed 
2.5.2.

Edit with IDLE still fails, as does a simple py file like junk.py (has 
five lines of simple math). That is executing junk.py or trying to get 
it into IDLE doesn't work.

For junk.py, I tried Open With->Choose default program. I selected 
idle.pyw. When I tried the new default for getting to IDLE, it 
complained it was not a valid 32-bit app. That's very strange.
