I just had a look through the installers for Studio, and stand alone installers stop at 4.23
Anything later requires the use of DIM.
Hopefully someone will grab the two latest versions using DIM, then convert (rip, modify?) them so that that they can be installed by all of us. Daz's intention is to eventually make Studio an online program so that they can make us pay (and pay, and pay, an....) for increasingly buggy software.
THAT's not gonna happen. The hackers (bless their little hearts) will make hacked versions available, just like they have for everything else.
