There is no solution unfortunately. I've spoken at length with Roccat tech support and they repeatedly say that their stuff doesn't work on a machine with Steelseries engine installed.
Yep. I found out as much from Roccat and Steelseries tech support. Here are their responses.
ROCCAT:
"The "Steelseries Engine" that you have installed for your Steelseries product, can unfortunately lead to a crash of the ROCCAT driver software. In the past we have already tried to get in contact with Steelseries to find a solution for the problem that the ROCCAT drivers are being negatively influenced by the Steelseries Engine. Unfortunately we never received an answer. To use your ROCCAT product normally, unfortunately the Steelseries Engine has to be uninstalled or disabled."
STEELSERIES:
"• Please uninstall the SteelSeries Engine, then uninstall Roccat software.
• Next, Plug in Apex and then the Kone
• Finally, install the SteelSeries Engine
If this works, then the problem was not with the Engine and the Kone, it was a problem with Engine and Roccat software. Unfortunately, if that is true then we won't be able to resolve it, as it is a software incompatibility with a 3rd party software. I hope that's not the case though so we can get this resolved."
I had already unsuccessfully tried the Steelseries solution. I ended up returning both the keyboard and mouse. Hope this helps anyone thinking about combining these. I will say that both companies responded to my emails very quickly so from that end I can't complain.
