Hi there,

I am trying to install Python on my computer but get some errors.

When installing, I get the message
Error:
"Python ha dejado de funcionar" (Python has stopped working).
But installation continues to the end.
In the installation I select "Add Python to PATH", but when typing "python" or "py" on the console, I get this error:
Error:
"No se encuentra el punto de entrada del procedimiento GetActiveProcesorCount en la biblioteca de vínculos dinámicos KERNEL32.dll" (Can´t find the entry point of procedure GetActiveProcesorCount in the dynamic links library KERNEL32.dll).
I have tried with different versions (2.7.15) (3.7.7) (3.8.2) but get consistently the same errors.

I have searched for some help in Internet and have tried installing previously the most recent version of "Microsoft Visual C++" (in my case, x86: vc_redist.x86.exe), but to no avail.

My system:
- Laptop ASUSF5GL
- Windows Vista Home Premium. Version 6.0 (compilation 6002: Service Pack 2)

My apologies if this is the wrong section in the forum (couldn´t find any better).
Many thanks in advance Smile
Find the appropriate installation instructions here:
and follow.
Thanks for your answer.
I have followed the instructions you suggest.
Same problem persists.
Any other idea?
Please show you installation procedure step by step, including all messaging.
I have sent an email to help@python.org and they recommended to install the last .msi version of Python (3.3.5).
That made the trick!!
Many thanks for your help.
