Inatalling Epic Games launcher, how do I choose install path?

I am trying to install the Epic Games launcher and it automatically chooses a place to install. Unfortunately that place is a hard drive that I don’t want to install on but I can’t see any way to change that. I just get a message telling me where it is going to be installed and buttons asking me to either continue or cancel installation. If I hit continue it tries to install… how do I fix this?
