Sorry, but I can't reproduce the problem. Copy/paste from the code above and:

Code:

pyuic4 -o test.py -x test
python test.py

Produces a Hello World screen with no errors. So, something is wrong with your pyuic4, but I don't know how to help.

Same for the hw.ui.txt, gives Hello World with a "Click Me!" button.

I haven't used pyuic for a while, but from what was posted above

Code:

pyuic4 -o test.py -x test

Compared to yours, there is a difference

Code:

pyuic4 -x benvin.ui -o benvin.py

To me it looks like you are trying to run pyuic from with a python console? i thought it needs to be run from within the dos prompt - also, the example has the .py first, and you put the.ui first....

a few bits, not got time to test and show at the moment though.

The reversal of the ui and the .py should not matter (as long as the .py follows the -o). That DLL import error and the "not valid win32 app" looks like PyQt itself is not installed properly.

My first guess would be that you are on 64-bit and the PyQt may be requiring 32. This came up with a quick google and it appears you aren't the only one with that problem.

There is a possible workaround in the second comment.. but as I don't have windows I have no idea if there's an easier way or that problems actually supposed to have been resolved by now (last post in Feb).
