Piosolver installation mistake

I accidentally changed the install destination folder when installing piosolver. I accidentally deleted where it was preset to install, so then I just chose the desktop and installed it. When I tried to use it I got an error. Then when I looked online I noticed some warnings about not changing the destination folder when installing.

I asked on piosolver's discord but got no response. But can someone explain how I can uninstall it and reinstall it so it will work properly.

I may have some technical difficulties as well because I bought a windows laptop and am installing it there when I have been mostly using a mac for many years. Thank you.
