some installers are more advanced, and check if the user installing is admin or not
if the user is not admin, the installer will install everything locally
if the user is admin, the installer will ask if he want to install only for this one admin user, or for all users (i usually see it asked like this for just you or all users)
also, i think we need to have more info on the dlls installed, like version number
and does anyone know which version of openssl is being installed, 1.1.1 or 3.0.3 ?
