windows installer x86-64 is the 64 bit version, just windows installer x-86 is 32-bit. But it's strange mysql complaining about python. Do you mean
mysql-connector-python? Note there you can choose between 64-bit and 32-bit versions of connector. Just download the one that match your python installation. In both cases I would go for 64-bit unless you have a reason not to.
