Hm I tried the key, it seems to work at first, but then it never comes up again under the help menu, it keeps saying register. BTW, the key they provided is the exact same key I was given by on Shareware_on_Sale in January 2015
Startup is slow, really slow, takes several seconds, The fonts are tiny on my hi resolution, it won't respond to Ctrl mousewheel or Ctrl Num+ or any of the usual zoom shortcuts.
And it refuses to open some zip that I have no problem opening in 7-zip, Bandizip, FreeArc and IZArc. Tested the zips in question - they are fine everywhere else but UlitmateZip.
Guess I pass up on this one - got enough archive handlers anyway. But thanks for letting me know.
