There is no requirement to install the anything before installing version 8. We don't have a game file labeled part 2 on this storefront, only V0.8. If you can install the Demo (Part 1) here you should be able to install the V0.8 one.
so if I download the part 2 version does that include everything from V08 update or do I still need that update
Yes Part 2 is the exact same as V08 at this moment.
