LAMMPS GUI Test version for macOS, Windows and Linux

This is something that is not caused by the executable, but rather by the installer. It creates shortcuts in the start menu and thus are set up to use the Documents folder. Can you try to locate the .lnk file in the start menu folder and see if you can edit it to use %USERHOME% or something otherwise reasonable as default location? I could then update the installer.

Question: When you launch LAMMPS GUI this way, does it open and run in a terminal window?
also from the “Run” dialog in the statusbar at the bottom?
