It seems that none of the included skins (e.g. Aero Metals, Aero Woods, etc.) work. Why not? And, why are they included in the program?
I have 7 64bit and I find the only way to use the aero skins in windowblinds is to first enable an aero theme under the default windows personalization option. I can then click any of the aero themes in windowblinds and they work. I don't bother doing that though because I never use them.
