How long is Win 10 available? That's a bad joke, isn't it.
I bought that crap. At least it was cheap, but still too expensive for something quite useless.
To be fair, OSX has been available for quite a while too...and ObjectDock isn't designed for that either.
As with any and ALL programs produced by anyone [not just Stardock] it is IMPERATIVE that one checks the posted System Requirements.
Unlike ALL Microsoft OS's prior, Windows 10 is [still] under constant revision which can preclude some programs from being compatible in the short term at least.
