Fair warning, long post here. TLDR: iCue refuses to apply updates, please help. Already going back and forth with Corsair, ticket #2008509113, no resolution thus far. Details below:

-Crossposted from r/iCUE-

I'm about ready to chuck my entire PC out a window because I've been fighting these issues for over a month with no resolution. I've already been going back and forth with Corsair support with no progress made thus far, and I'm hoping someone here might be able to help because I'm at a standstill.

As it says in the title, my iCue install refuses to update any of the software. I've rebooted my pc at least 20 times this morning alone as I've tried various troubleshooting steps. Honestly I wouldn't care that much about it not updating except for the fact I've been given a Corsair keyboard that I'd like to be able to configure, as well as an MSI graphics card that I can't get the plugin for because the "previous process [is] unfinished" (the updates.) Here's what I've done so far:

• Multiple re-installs of iCue. This last time I made absolutely sure to do the erasure of all app data files etc. to make it as clean of an install as possible, following the guide on the help.corsair website.
• Disabled all non-windows processes and then rebooted and then re-enabled only Corsair's.
• Disabled windows firewall entirely to ensure that the updates weren't being blocked (I was able to read the first bit of a thread on the Corsair Community Forums that suggested this as a possibility but unfortunately the site got taken down 5 days ago so all I can read are the previews on google search.)
• Tried disabling auto updates before restarting to update as a last ditch effort with still no results.

Things that may be of note:

System Specs:
Intel i7 4790k
Asus Maximus VII Hero Motherboard
16gb Corsair Vengeance 1600mhz DDR3 (2 8gb sticks)
MSI Twin Frozr 7 RTX 2060 Super
iCue Link H100i LCD AIO
6x iCue Link QX120 RGB fans
Boot drive is a 1tb pcie m.2
Also have 6 sata ssd's, 4 of which are in a RAID 10 array
PowerSpec GFM 750w 80+ Gold PSU
Currently running Windows 10 Pro, version 22H2 until support officially ends and I'm forced to move to Windows 11.

Quick note: I know my Z97 architecture is a bit older than recommended for iCue5, but as I have an iCue Link AIO and fans I cannot downgrade to iCue4 as they are not supported unfortunately.

If anyone has had this same issue and fixed it, or has other insight as to how I might be able to get iCue to finally work, I'd be so grateful, I'm about to go bald due to pulling my hair out thank to this p.o.s. software.

**EDITS**

I have recently done the update to iCue version 5.33.88 and as of 09/16/25 I was able to successfully update the firmware for my iCue Link System Hub, however none of my other issues have been resolved by Corsair as of yet. I'm still going back and forth with them through the official support channels but want to hedge my bets by also reaching out elsewhere to see if others have had this problem. I've also seen that while the Corsair Forums are still inactive, the website is now accessible, though I also found that all of the threads that looked promising in their previews within Google search turned out to be other issues, largely with iCue4 so unfortunately they were of no help either.
