Binary Packages

These binary installers for Windows contain everything needed for PyQt4 development except for Python itself.

Unfortunately it is not possible to use both the PyQt4 and PyQt5 installers at the same time. If you wish to have both PyQt4 and PyQt5 installed at the same time you will need to build them yourself from the source packages.
