Can't install because path already exists (MacOS)

Hello, I am a first year student trying to install this for one of my courses and every time I try to install the wizard it fails and I am met with this prompt,

‘/opt/anaconda3’ already exists. Please, relaunch the installer and choose another location in the Destination Select step.

I have tried quite a few things but nothing seems to work. Please any and all help will be greatly appreciated
