According to the info you give, I have done the following steps:
1. Upgrade to SP2 first.
2. Install the CRT update.
But the result is still the same, nothing happens after double click the file python-3.6.1.exe.

I deeply appreciate your help. It looks like that Vista has to live with Python 3.4 for its rest of life:-)
