[PyQt] Re: PyQt 4.4.2 GPL installer / missing DLL

[Pierre Raybaut]

Hi Phil,

I did some tests, and apparently when files located in
"C:\Python25\PyQt4\bin" are all moved in "C:\Python25", everything is
working well without adding any directory to PATH, and it does not depend on
the Python root path (which default value is "C:\Python25", but I tried to
change it, and it seems to be working as well).

So... you may expect my question: could you implement this in PyQt GPL
installer? (or is there another issue which I am not aware of?)

Thanks,
Pierre

PS: in the meantime, my installer will manage this itself, but I'd be more
than happy to run silently your installer...
