ISO file corrupt???

Hi, I’ve downloaded the ISO file from http://get.qnx.com but when I unpack
it with WinImage and burn it on a CD I cannot install any software from the
respitoire (sorry it’s not the correct word, but you understand what I mean)
And all the docs (*.html) are empty, does anybody know about this problem,
or…
please help??
