First, download the program from Felo's project page on Sourceforge as an EXE file, and start it. There are two alternatives: You can start is as an ordinary user or as an administrator. In the latter case, it is installed for all users on this computer.
Installation itself is very simple. It should be sufficient to click on “Ok” a couple of times. The uninstallation is equally simple but assure that you are logged in on the same account you used for the installation because otherwise, Felo may not be completely removed.
