True, but it should have a lot to do with Python27.  Some good news is 
that unlike previous attempts, I can actually see IDLE as a choice on a 
right-click of a py file. However, a spinner icon appears for about 5 
seconds and then disappears.

I have no Python of any kind in System32.  I uninstalled 25 months ago. 
As far as I can tell, there is not a scrap of it left.

Hmm, I made have made a mistake about a 25 dll.  When I rebooted last 
night, I though I recalled 26. I'll reboot again in awhile and verify 
that. Yikes! No need. It's 26dll.  I wrote it down after my first boot. 
My second was last night.

Forgetting about 25 (32-bit), per above, I installed a 64-bit version of 
2.7.2. python-2.7.2.adm64.msi.
