I think they have done something with their VISE installers, so now they only work in OS 9.2.2 and nothing earlier. I think installers are a very bad idea (they add to the cost and time required to distribute an item, and they invariably cause problems for people), but Daz is stuck on them for some Machiavellian reason. Daz could save alot of $$ and man-hours if they did it like everybody else and used zip files which expand to Runtimes in the place of our choice. Their use of installers makes them look like they're stuck in the 80s.
