Idk if this would help but have you tried downloading the firmware update for the wow mice off of the steelseries website?
its under the engine tab and under firmware update labeled as " World Of Warcraft® MMO Gaming Mouse"
I downloaded that along with the steel series 2 engine and everything works perfectly.
Hi, I have World of Warcraft MMO gaming mouse (62006) and the Wireless gaming mouse (62220-01). And have some problems with them. With the wireless mouse is the scroll button, when I scroll down it goes up after a few lines and keeps scrolling up and down at will. And with the other one, each time I move the mouse or left-click it goes back to the previous web page as if I hit the back button. The software seems not working with Win10 won’t start at boot. For the wireless im using SteelSeriesEngine_2.9.2014.1.exe and for the other one wow_mouse.exe.
I have to admit that in the end I gave up with the WoW mouse functionality as Blizzard have said that as it’s now old and long out of production they won’t be supporting it going forward.
You can get it to work with the software Steermouse 5, but you have to pay for this. In the end I just bought a Steelseries Rival 500 and this works fine.
A shame, but there you have it.
