I'm running Windows 8.1 64bit but have Python 2.7.10 32bit. Now I'm trying to install PyQt using Windows installer. What version should I download?

PyQt4-4.11.4-gpl-Py2.7-Qt4.8.7-x64.exe    Windows 64 bit installer
PyQt4-4.11.4-gpl-Py2.7-Qt4.8.7-x32.exe    Windows 32 bit installer

I have 64bit windows but 32bit Python and I want to make a 32bit executables.
I think that I should install 32bit, is it true?
Yes I would guess you're right since python will link to PyQt they should be based on the same architecture !
What version of PyQt should I install (32 vs 64)
