I'm having a similar issue.
I just got this Strafe Mk2 RGB, and during the iCue installation, I accidentally stopped the download and had to resume later. The program never opened for me but is in the back ground apps on task manager. I can close it, but i cannot open iCue.
Deleting it and reinstalling it doesn't work. neither did deleting appdata files, or going into the Registry and deleting every single corsair file that would come up in the search. nothing works.
I decided to download the old program, Corsair Utility Engine, and SOMETIMES it will read my keyboard and i can use all its features, but never on start. and if it does read it on start, the keyboard has delayed responses, no response, and sometimes get its self stuck on a key. I tried to update Cue into iCue, but nothing happens and i just lose the old software and have to re download it. I have tried updating this "up-to-date" firmware on my key board but that doesnt do it. if someone tries to tell me try a different USB slot im going to lose my mind cuz thats what every thread says and they all say nothing happens and i can tell you a head of time, i tried, nothing happens. I am currently using two USB 3.0 slots.
Please help. I'm going to factor reset my computer soon to see if that works, and if it doesn't im going to return my birthday gift and first ever high end keyboard i've ever had and waited years for. Been stressing over this since I got it a few days ago, and heart braking would be the word to describe this experience.
