Sorry to be so late pulling into this discussion

As regards the reasoning behind the free offer from SAZ3S, here is the Official response from DAZ_BHowell, DAZ_Product Mangement.

"Our reasoning in making the suite available for free is simple; increase the number of people using our software and broaden the base of potential customers and content creators. "

 

And BTW, anyone who is taking advantage of this free offer and who finds that the download is lacking a suffix should just right click to add .exe to the downloaded file. Our servers have been so hammered with the number of people taking advantage of the free software that DAZ3D has had to farm some downloads out to other servers, and these downloads seem to be missing the .exe suffix.

The greatest part of wisdom is learning to develop  the ineffable genius of extracting the "neither here nor there" out of any situation...."
