My Library looks different than others?

[Anonymous]

So, recently I tried to put in a 4-sash wide window. A little looking around in my window library showed me only up to 3-wide units.

Some googling about this brought me to the conclusion that I SHOULD have the option to put in a "Horizontal multi-sash window".

I do not have this option. Further, my window library appears very different from all the examples I see online.

Does anyone know what is happening here?

This is what my window library looks like:

And this is what I see online when searching for multi-sash windows:

Why is my library different? I do not have a "Basic Windows" folder and I do not have the Horizontal Multi Sash Window option.

I think you have the US library. Horizontal multisash window is available in the INT (and INT based) versions only.

...So you are saying I cannot make a window with more than 3 mulled units..?
