The Windows 32-bit ActiveState Python version must be installed, not the Windows 64-bit ActiveState Python version. If you install the Windows 64-bit version,otherwise you will need to purchase a Business Edition license from ActiveState, in order to install some Python modules which are "locked".
Many other Python modules can be installed via pypm. See: http://code.activestate.com/pypm.

This step is completely optional, and not necessary for using Twisted for the class exercises.
If you ever want to build Python modules which have native code in C, you will probably need to have the Microsoft Visual C++ compiler installed. It is best to get a license and install the full version of Visual C++.
If you don't have the full version of Visual C++, you can try installing the free Visual C++ Express edition from Microsoft.
