Writable path problem…

I downloaded vara ac I already had vara Hf that I use for winlink, but when I open vara ac and then try to save the ptt settings it tells me to choose a more writable path.🤷‍♂️ then I’m not able to save my settings and get the radio to key up. I know this is a noob question but how do i fix it? ( and please don’t say find a better writable path) 😅 I need a little more detail than that to understand 😅🤦‍♂️🥴
