No problem.

Yesterday, I downloaded "PyQt4-4.10-gpl-Py3.3-Qt5.0.1-x32-2.exe"
and installed it on my Windows 7 Pro box after having removed
a previous version.

No problem with the installation.

I quickly tested it with one of my interactive Python interpreters
and got an error "from PyQt4 import QtGui, QtCore" saying, that the
DLL cannot be found.

Something similar to what Detlev Offenbach reported on
the PyQt mailing list. Although, I'm not using Qsci.

Strangely, I had not problem (if I recall correctly) with a
very basic application (QMainWindow + QLineEdit).

I had no problem with the demo (I only lauched it).

I did not spend to much time in investigating further.

It's the first time I see such an error; usually, no problem.
