3D Box Generator Action set & Templates

I didn’t try it yet, the comments for sure look promising. What if the boxes I orginally designed aren’t as wide and as tall as the template you provide, is there anyway to adjust it?

Mhh, I bought it but I have Photoshop CS5 .1 for Mac and it doesn’t work. Action stops because “The object “layer “3d box”” is not currently available.”

Any help??
