When I try to download epic installer its says this specific account already exists

I have been trying to get epic games installer since September and it wont work, it says, “The specified account already exists” I really want to play games! HELP

Probably you’re trying to register an account with an e-mail that’s already registered?

No, it was as I was installing. I also tried that
