#81879 — Is Python installer/un-installer buggy on Windows?

I am using 32-bit Python on a 64-bit Windows. 

Edit with IDLE is missing from the context menu. I am working on Windows 7. I have searched on google a lot and have tried everything said in superuser, stackoverflow etc. I have even tried re-installing Python. I am now only left with re-installing Windows itself which I don't think is a good idea.


Shouldn't the Python installer be able to fix this thing? 


I have both Python 2.7 and 3.4 installed but I uninstalled both and tried installing one. No use. 

Is there some problem with Python (un-)installer on Windows? I am asking because I have multiple IDLE in my Start menu one of which starts to install Python 3.3 in the default location (which I had earlier).

I suspect the problem is with the registry.  Only one version of 
Python/Idle can be connected to that entry.

Definitely not.

Did you check "[x] make default version", whatever the exact wording is?
How did you uninstall, and reinstall?

Occasionally.

I do not understand how a Start menu entry can begin an installation. 
It is the result of installation.

Yeah, the problem seems to be with registry as every solution seems to be fiddling with registry.

I know that reinstalling OS is a really bad idea. But I have tried to find a way to solve this for months now. I have started a bounty on superuser also for the same in the question "Python IDLE disappeared from the right click context menu". And asking on these groups was the last thing I can think of.

I uninstalled via the Control Panel. I installed via the official Python installer for Windows.

I also don't understand how a start menu entry can begin an installation but it is doing just that. Now there seems to be 4 IDLE entries in my start menu. Two are valid (2.7.8, 3.4.2). The other two are previous installations of Python 3.4  that I did at different locations but removed later. I have stopped running IDLE from the start menu due to this. Because I am never sure whether it will re-install Python 3.4 at those old locations or not. Even right clicking those entries in start menu causes the installations to start. So I cannot even find the physical path of those entries.

Maybe too much fiddling with the registry has caused it. Not sure about that.

One can edit the registry directly with regedit.  If you try it, follow 
the instruction to first make a backup.  Look for a regedit tutorial on 
the web.

To me, this specifically indicates a registry mixup.
To prevent installation, delete or rename the downloaded install files.

Delete those two.

With Win7, I keep the two current installed Idles pinned to the taskbar. 
  (I also have all three Python development versions pinned.)  With 5 
different builds of Idle to edit with, I open one or more first and then 
open to edit (often with Recent files).  I almost never use 'Edit with 
Idle'.
