Thanks birdy!!!
Yes it is a old bug in LW 4.x.x thats cause you to apply the choosen skin twice before it change it, but has nothing to do with my skin installer and can only to be blamed on LW for this...Have removed two skin from the installer since they already was listed there!And thanks to Lotr for this discovery about the two skin that have different name but was in fact the same skin....I have tested the skin installer and the skins, and it works fine for LW 4.18.8 Pro so fare I can tell!
