Thanks everyone for the suggestions. I was able to fix it!
The removal software didn't work, but installing the original IMVU client, uninstalling it, and then using CCleaner's registry cleaner (which I know isn't exactly the safest but... it worked?

) got rid of everything.
I recorded my computer giving me that error when I tried using the Windows remove program just to show it happening? Again, I am unsure why it was doing that.
But yeah, thank you! I am grateful for IMVULite
