Thanks a lot to everyone who can help me solve this problem. A friend of mine downloaded the mirror 1 link for Project Icarus but is completely unable to finalize the installation. When double clicking on the "setup" file, once the installation is over an error message pops up saying the following: At the end is said in french the operation asked necessitates an elevation. Not sure how to properly translate that in english. If you could give me some help, I'd be eternally grateful. Regards.
