The reason why people are correcting you on Poser Pro 2012 is because, supposedly, the next Poser version will be Poser 12, likely not even being made yet, however Poser Pro 2012 was two versions ago. They're just trying to avoid confusion.

Basically we had (if I remember correctly and not counting spin-off versions like Debut and Game Dev):

Poser 1 ~ 7 Poser 8 / Poser Pro Poser 9 / Poser Pro 2012 Poser 10 / Poser Pro 2014 Poser 11 / Poser Pro 11

Which is super confusing because Poser has changed owner several times and they weren't consistent with their naming. But everything now points to that the future one will be just Poser 12, as Bondware has turned both Poser 11 and Poser Pro 11 into just Poser 11.2 - it doesn't look like they'll be making two separate programs for the same version.
