All head-sets are available as self extracting RAR files.
I switched to WinRar as this packer has much better compression rates than winzip.
Also it incudes much more (and better) features for a much lower price.
And last but NOT least i need to say winzip and all its buggy and useless
wizards SUCKS. These wizards are not able to setup a screen saver, that
consists of more than one file, in a correct way.
Asking winzip support about this gives the answer: You may need to include
a readme file. BUT WHO reads the f**ckin readme files ??? And why should the
user read it if he was told by this ´fabulous winzip wizard´ it would be
able to install the saver. So i say: forget this commerce-overdosed-bulls**t...
You DONT´T need to have installed Win-RAR to extract the head-sets,
but if you are interested... try Win-RAR. It's easy, simple to use and it WORKS !!!.
