ryzen5000

I already tried installing it around 50 times or so from my side, but after reading this post I decided I'd try it one more time.... and it worked. I didn't change anything.

I got mine to work by installing v3.34.161 of the iCUE software. I couldn't find it on their website but manually adjusting the version in the download URL worked: http://downloads.corsair.com/Files/CUE/iCUESetup_3.34.161_release.msi After installing this version, do a full shutdown of your PC (i.e. don't tell it to restart, do an actual shutdown) and after powering back on you should now be able to control the commander core in the iCUE software. Note that the software still prompted me to update the firmware and it still fails when attempting to do so, but with this version of iCUE you can simply ignore it and control the capellix anyways.

I also am having the same issue. I just built a PC today with a Corsair 500D case w/ included Commander Pro and an H115i Elite Capellix that required a Commander Core. I plugged both the Pro and the Core into my 2 motherboard USB 2.0 connectors and both were initially recognized by the iCUE software, but the Commander Core is no longer recognized after failing to install firmware v 1.6.135. When I click update the Commander Core, the progress sits at either 0%, 7%, or 10%, and eventually fails and disappears from the recognized device list.
