I see that Vue Infinite 9.5 was released back in summer 2011. Vue has come a very long way since then (but can still read and load Poser files). I'd definitely install a trial of the latest Vue and see if it might be worth it. Otherwise you would have to junk a lot of skills, knowledge, and perhaps also Python scripts. Also, I believe the subscription gives you access to E-on's PlantFactory. I seem to remember that that they will also unlock your purchased Cornucopia stuff (though I may be wrong on that, or out of date).

No Windows 7 though. The target for Windows 7 would be Vue 2021.1 R6.1. I'm not sure they'd let you subscribe to that though.

Terragen is still around and had a lot of effort put into clouds a few years ago. But probably not as easy as the 'stylised but realistic' Vue atmospheric system and one-click presets.

Gaea has been mentioned above, and I think it had a major update recently too?

There's also various real-time software such as World Creator (or is it World Machine? I can never remember the difference), Instant Terra etc and after that you're into the real-time proper game-engines such as Unreal, Unity, some 2D/3D artists still us that old (Half Life?) engine whose name I can't recall (Source Engine?) and do nice things with it. I even see people still making pleasing planetscapes on DeviantArt with MojoWorld!
