Install Issue EpicInstaller 13.3.0 trying to install on a drive I don't have

I’m excited to get started and new, trying to install Unreal Engine (EpicInstaller-13.3.0) and it’s trying to find drive Z. I’m not sure what version the latest installer is trying to install. All I know is that I don’t have a drive z. I’m curious why it wants to install there? I’d like to tell it to install elsewhere but the installer immediately fails and ends without an option to choose a different drive. Any suggestions? Thank so much!
