Execute the downloaded file. The setup program copies only some files (the program, license, todo, changelog) to the C4FIBS directory and creates some shortcuts. If you start c4fibs it creates a log and rc file in the same directory. Nothing is saved in the system registry or in an other place on your system. To uninstall the program execute the uninstall program from the start menu.
