I found this on SanDisk’s site and thought that I would paste it out here so that it might help many of you. Go to the link below for more but that is the computer systems which it supports. I can tell you that it also works on Windows 10. Mine is currently connected to and running on win10. I plugged it in, and had trouble. After a reboot or two things straightened out. It is reading all of the card drives. I did look at device mngr, tried scanning for new hardware or hardware changes, etc and that did not help, unless doing that plus plugging it in with a card in it with the one or two reboots afterwards did the trick. Hope it helps someone.
SanDisk card readers support Windows Vista , Windows XP SP2 and Windows 2000 SP4, Windows 7.
Mac users there is a link there too
