[PyQt] PyQt4.QtCore not a valid Win32 application - with windowsinstaller

[Sibylle Koczian]

Hello,

I posted this a week ago, but didn't get any answer at all. So I'm 
trying again, because I really would like to use PyQt again, and I'd 
definitely prefer the Windows installer, if at all possible.

Is the windows installer supposed to work with 64 bit Windows and 64 bit 
Python? On the Riverbank web site I don't find anything to the contrary, 
so I'd think it should work. Right or wrong?
