Smart Fasteners/toolbox can't use in solidworks

Hi support team,

I'm having a Problem were I'm getting an error message which goes like this;

Error: Smart Fasteners requires SolidWorks Toolbox, which is not present.

now I didn't try much to fix this because I don't have a lot of time. But I checked the folder were SolidWorks data exists with the toolbox items, everything is there but somehow solidworks can't link these 2 things together. And yes it is located in the C:/solidworksdata folder. Just cant use smart fasteners. Do i have to open up something else before using smart fasteners like the toolbox itself? or what? i don't really know were to look, please help.
