Calc Style is Missing from TexLive

I am quite new to the tex space. I recently installed Latex in conjunction to texlive (easy editor). I need to write a paper in astronomy and astrophysics but when I use the required template it says calc.sty is missing.

I am running this on Windows 10 and have been searching the internet for hours but can’t find a simple way to have this style installed on texlive.
