I NEED HELP I need to take off vocals of a song before tomarrow

Hello, I need a FREE software to that takes off vocals of a song (that is not gana spam my laptop with junk and give me virusis) PLEASE HELP, i need one like now. The one my aunt got just kills the song (sure it takes out the vocals but then you cant hear any “treble” things)

Well?

(I dont care if this topic gets deleted or locked just please let someone first answer my question, I have like 7 people counting on me to get this song to work)

I did some very quick research (I wish I could help some more, but I’m really busy). Many anecdotal sources say that acapella separation is impossible. One guy suggested playing an inverted instrumental track over the song which, in theory, should leave the vocals by themselves.
