They keep telling you to upgrade your stuff because the new stuff is so unbelievably better than the old stuff it's not even funny. PCS2 _should_ be a replacement for Modelview AND PCS1, so really, you're actually getting rid of a program instead of adding one. If your dad is really crazy, tell him the other option is to get a compiler from Microsoft (probably the only place he'd trust, and they have a decent free one), and get source code access for PCS2 and compile it yourself. Then decide which one seems more attractive. But seriously, these older programs are quickly moving into unsupported territory, it's just that a lot of the docs haven't caught up yet. The forums however have, as virtually everyone is already making the switch to PCS2 due to being tired of how buggy or slow or incompatible the old stuff is. If you need just one good reason to switch to PCS2 for your dad, here's one: The de facto standard texture for ships is pretty much DDS nowadays, and neither Modelview nor PCS1 support displaying those, but PCS2 does. So now you've even got a pretty damn good reason.
