[PyQt] PyQt Installer Does Not Run

[Ben Thompson]

Hi,

I just tried to install PyQt for Windows Vista 64 and Python 2.6. The 
latter is "installed" in the sense that I can type "python" at a prompt 
and get

ActivePython 2.6.4.10 (ActiveState Software Inc.) based on
Python 2.6.4 (r264:75706, Jan 22 2010, 17:24:21) [MSC v.1500 64 bit 
(AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.

but when I try to install PyQt I get

This copy of PyQt has been built against Python v2.6 which doesn't seem 
to be installed.

I've googled a bit and looked in the searchable archives but can't see a 
solution.
