[PyQt] Newbie needs help in installing PyQt

[Dick Moores]

Win XP, Python 2.5.1

===============================
Binary Packages
The binary installer for Windows contains everything needed for PyQt
development except for Python itself.

PyQt
Qt (with database support for SQLite3 and ODBC)
Qt Designer
Qt Linguist
Qt Assistant
pyuic4
pylupdate4
lrelease
pyrcc4
QScintilla
PyQwt
Qwt
eric IDE
=================================

So I downloaded "PyQt v4 GPL for Windows and Python v2.5"
using the link just below the above. It seemed to install OK, and
shows on my Start menu. However, Eric won't load. QT Assistant hangs.
And much of the documentation "can't be found", or words to that
effect. Qt Designer does load.

Advice, please.
