I've always been an iCue fan. I have no problems with their software. 

Yeah I dont get it.. my original X20 had no issues updating. It broke, got an RMA, would not update.. told them, they sent me ANOTHER mouse.. and it also will not update.
Lame.

Unfortunately, it is likely due to the operating system having some compatibility issue with the software. 
 
Can you please see if your mouse will update on another system if available?
 
I assume Windows 11?

no its windows 10 but i got a new problem now which i suspect has to do with the update , i just got my z20 KB and now the x20 keeps disconnecting.
my z20 updated just fine (had to rename the firmware folders back to original) but the mouse update still crashes
so the mouse is useless or the keyboard is useless
feel so stupid atm for choosing evga
