Dude -- just replying to random, absolutely unrelated posts gets you nowhere. Please stop.
And about your questions:
1) See OP for keys to unlock features
2) Depends on whether you want more security (not ticking boxes) or all the features (ticking boxes)
3) All *.VAR file have to go into "AddonPackages" or any subdirectory of that folder
4) You need dependent filesets for most scenes/looks to work
And finally: please use Google to search for some basic VaM tutorials, or use the VaM Hub as it has some very useful information as well. I even sent you a link to a playlist on Youtube with lots of tutorials. Please read/watch those tutorials before asking more questions. Thanks.
P.S.: I also told you to start "slow" by downloading a single look/scene to make yourself familiar with VaM. And now you're posting screenshots of a 66gig Torrent file with all kinds of stuff you don''t even know how to use, which is exactly the opposite of what any new VaM user should do. Keep doing it, and you will fail 100%. Why keep asking questions, and then don't read the answers or follow those suggestions (I can tell you didn't read or watch a single tutorial yet, and you're downloading a 66gig torrent with thousands of scenes already)...?! Well, I'm out, good luck on your VaM journey ;-)
