Hi Simon, Running “C:\msys64\msys2_shell.cmd -mingw64 -mintty" has the same effect as clicking on the "MinGW-w64 Win64 Shell" shortcut. It is the proper way to start an mingw64 shell. If you have run "pacman -S" to update the MSYS2 packages before, then the old shortcuts setup by the MSYS2 installer may cease to function, and you can put a new shortcut on your desktop with that command.
