Skins are multi-language, so it should change the design file (msgsres.dll) and not the language file (msglang.dll). If the installer is Spanish, the skin should be in your default language .

Skinning hasn't changed for 8.5 really, I suggest reading current tutorials to get an idea how to skin and adjust them to the specific changes. Check out my full tutorial on how to skin Messenger.
