Changing System Tray Icons in CustomizerGod... NEED HELP!!!

hello, all! I'm having trouble changing my system try icons from Windows 10 over to Windows XP. here's what i got so far:

so far, i have the volume icon somewhat working? I'm using CustomizerGod and I need a little help with it... 

I only have a few of the icons changed, but whenever i use the mute icon, I get an error message:

I'm not sure why this is popping up??? the file itself is an ICO file that's 32x32 pixels, sooo... idk what the problem could be :/

there's also the problem of me trying to change the battery icons as well??? I get an entirely different error message and it makes me even more confused:

i always end up X-ing this pop-up and I try to change the icon anyway just to see what happens, and I get this error message in response:

I'm really not sure what to do... I have tried finding my imageres.dll file and i did find it! the thing is i dont know what to do with it... do i try and edit it?? or do i put it somewhere??? I made an extra copy and saved it to my desktop just in case, and I downloaded ResTuner in case i do need to edit it... please help!!!! (╥﹏╥)
