Add .dic file in Windows

Good day everyone.

So my parents use LibreOffice on their Windows 7 PC, now I wanna add Armenian spell check, which are .dic and .aff files, but the question is… WHERE to add ?

I know how to do this on Linux, but no idea about Windows…

Thanks.

Hope this link helps you.
