I'm not going to quote anybody for this, but yeah, that DAZ installer is idiotic.
It also causes error messages in Windows 7: "This program may not have installed correctly", which will pop up after the installer is finished. I haven't seen any other installers do that, certainly not any modern ones.. And the DAZ installer isn't even that old, certainly nowhere near as old as Deep Paint 3D, which I just installed the other day and which doesn't cause that error message.

Of course you can easily enough defeat any runtime stupidity it wants to foist upon you by installing to a temp folder first, which is what I do, but I can't see a single reason why they can't just use a zip file, along with a ReadMe of where to put everything.

Yeah I know, it's for the n00bs. But honestly, I don't care. Let them RTFM. Let them either learn or have a hissy fit cryfest. After they finish crying about not knowing what to do with the files, they'll figure it out and they'll ultimately be better off for it.

That's just for the normal stuff from their store.

Don't even get me started on the V4 and M4 installers. They reached levels of idiocy far beyond anything I would have thought possible with that maneuver. Whoever at DAZ thought that was a good idea needs a good slapping around.
