I installed kdenlive in fedora 23 gnome , kde , mate , xface . When I frist start it . It wants me to config it . But when I get to the part where the codeact are there no check marks or red x . So I click next next then where it would show where it would find the software like vlc . But there no ckeck mark or where the red x Where is should be . But if I try it on arch , ubuntu . It works just fine ..
