you need to either compile a static build
or give us more .dll files
its up to you
more .dll files would be easier for you
but a static built wallet would be much better.
That is all the .dll files, it is working for other people so we cannot figure why it won't work for you. Also you cannot static build with qtwebkit.
the only explanation i can think of then is that there are missing .dll files.
well for me i don't need a windows wallet i can use my linux pc
but for others...
