[Idle-dev] newbie - IDLE won't start, socket error, Vista, 32bit

[Debbie Paul]

Hi All,  Newbie, trying to learn Python. os is Windows Vista, 32-bit 
machine. Used Installer pkg from helloworldbook.com
includes Python 2.5.1, Tk 8.4 and IDLE v 1.2.1 (and other stuff).

Trying to launch IDLE from Start Menu icon. Socket error: permission 
denied. IDLE's subprocess didn't make connection. Either IDLE can't 
start a subprocess or personal firewall software is blocking the connection.

Trying to start IDLE from cmd line:
c:\Python25\python.exe c:\Python25\Lib\idlelib\idle.py (or 
c:\Python25\pythonw.exe c:\Python25\Lib\idlelib\idle.pyw)
gets:
IDLE Subprocess: socket error: Permission denied, retrying....
IDLE Subprocess: socket error: Permission denied, retrying....
IDLE Subprocess: socket error: Permission denied, retrying....
IDLE Subprocess: Connection to IDLE GUI failed, exiting.

Traceback (most recent call last):
** IDLE Internal Exception:
Traceback (most recent call last):
    File "C:\Python25\lib\idlelib\run.py", line 82, in main
       exit()
    File "C:\Python25\lib\idlelib\run.py", line 208, in exit
       del sys.exitfunc
AttributError: exitfunc
Traceback (most recent call last):
    File "<string>", line 1, in <module>
    File "C:\Python25\lib\idlelib\run.py", line 107, in main
       exit()
    File "C:\Python25\lib\idlelib\run.py", line 208, in exit
       del sys.exitfunc
AttributeError: exitfunc

Tried to run with firewall turned off. Same problem. Tried to run as 
Admin of computer, same problem.
At cmd line, ping localhost gets 127.0.0.1 ok. Is problem Vista 
permissions?, RPC (on Automatic) or RPC locator (set to Manual), 
firewall?, typo in code? I see other people manage to use this 
downloaded package. Kindly suggestions for frustrated newbie please. 
Thanks, Deb.
