mysql for python 2. 7 says Python v2.7 not found

I met the similar problem under Windows 7 when installing mysql-connector-python-1.0.7-py2.7.msi and mysql-connector-python-1.0.7-py3.2.msi.

After changing from "Install only for yourself" to "Install for all users" when installing Python for windows, the "python 3.2 not found" problem disappear and mysql-connector-python-1.0.7-py3.2.msi was successfully installed.

I guess the problem is that mysql connector installer only looks for HKEY_LOCAL_MACHINE entries, and the things it looks for might be under HKEY_CURRENT_USER etc. So the solution that change the reg table directly also works.

The Solution I get for this problem is

I have found Adding Python to Registry, the script as follows applicable for python v 2.0 and above: Register a Python Interpreter

import sys
from _winreg import *

# tweak as necessary

version = sys.version[:3]
installpath = sys.prefix
regpath = "SOFTWARE\\Python\\Pythoncore\\%s\\" % (version)
installkey = "InstallPath"
pythonkey = "PythonPath"
pythonpath = "%s;%s\\Lib\\;%s\\DLLs\\" % (
    installpath, installpath, installpath)


def RegisterPy():
    try:
        reg = OpenKey(HKEY_LOCAL_MACHINE, regpath)
    except EnvironmentError:
        try:
            reg = CreateKey(HKEY_LOCAL_MACHINE, regpath)
            SetValue(reg, installkey, REG_SZ, installpath)
            SetValue(reg, pythonkey, REG_SZ, pythonpath)
            CloseKey(reg)
        except:
            print "*** Unable to register!"
            return
        print "--- Python", version, "is now registered!"
        return

    if (QueryValue(reg, installkey) == installpath and
            QueryValue(reg, pythonkey) == pythonpath):
        CloseKey(reg)
        print "=== Python", version, "is already registered!"
        return

    CloseKey(reg)
    print "*** Unable to register!"
    print "*** You probably have another Python installation!"

Save it with any name. Run it from python interpreter and Thats ALL!!

This problem mainly comes with 64 bit windows. download MySQL for python 64 bit on this link http://www.codegood.com/archives/129 and download MySQL-python-1.2.3.win-amd64-py2.7.exe (1.0 MiB) This will install MySQL for python.

Windows 10 (64bit):
Indeed, I've had a similar issue and couldn't install the python 2.7 connector for MySQL.

Prior to this I've installed Python 2.7.15 with the Windows x86-64 MSI installer,
this was while I had Python 3 installed on my machine.

The Windows x86 MSI installer did the trick, I've installed it to override the previous version of Python 2.7.15, then installed the connector (this time it gave no error messages).

Then rechecked the status in the MySQL installer and voilà:
