iCue installer/uninstaller not working

Hi. I use Corsair iCue. Tried to update (iCUE 3.33.246 release). Wouldn't update.

Then tried to uninstall. Wouldn't uninstall.

I used a third-party uninstall to power-uninstall iCue. It worked for uninstallation, but now I still can't install it.

Even tried installing using the Administrator account. No luck.

Keep getting this same error for everything I try. Very frustrating. No forum solutions I've searched online worked.

Now, I have NO updates, and NO iCue software for my Corsair-brand gaming mousepad/mouse.

Here's a screenshot. Please help. I keep having issues with iCue updates.
