"unable to create user config directory   Z:\.idlerc   check path and permisssion"

It through out this error, when I try to launch the IDLE not as an adminnistrator acount. There is an networed disk memory Z: on my computer

this error is caused by configHandler.py script in the Lib/idlelib directory. Here is a solution: https://www.experts-exchange.com/questions/24006687/Invalid-Python-config-directory.html

This is a duplicate of #8231.  But before I close this, when you do 
> set
in the console (command prompt), what HOME* variables are set and is USERPROFILE?

In python, what does 

>>> from os.path import expanduser
>>> expanduser('~')
show?

Hi Terry,
Sorry,  I missed your resply because it was buried in my trash email.
Here are the configuration in my PC:
HOMEDRIVE=Z:
HOMEPATH=\
HOMESHARE=\\nt3.imec.be\zhai65
LOCALAPPDATA=C:\Users\zhai65\AppData\Local

USERPROFILE=C:\Users\zhai65

In python
>>> expanduser('~')
'C:\\Users\\zhai65'

I partly bypassed the bug by following the instructions shown in my
previous link.
