Quote - i have Poser 6 but i will install this free version on a second computer for my son.Did someone  know if this free one included all Services releases?Thanks

Yep! It's patched all the way to SR4. I've downloaded and installed it twice with two new free licenses which gives me three good licenses total because I registered a second email to the site and got a second license.

These two new license on top of my original from Poser 4 & Poser 6 gives me three to use when it's time to upgrade to Poser 7 or whichever version ends up having network rendering capabilities.
