# How do I install packages in TeXLive on Windows 10

I tried to install packages like numinsec.sty to Texlive on Windows 10 by copying the files in ‪C:\texlive\texmf-local\tex\latex\numinsec.sty. But Texlive can not find it when compiling. What is the problem?

Is the installation of packages on TeXLive similar to MiKTex in which you just copy files into a localTexmf folder and add that folder to MiKTex directory? Thanks.

• Note that numinsec is already part of TeX Live (at least TeX Live 2020). Aug 14, 2020 at 17:06
• No, I am using TeX Live 2017 Aug 14, 2020 at 17:18
• Did you run mktexlsr? Aug 14, 2020 at 17:20
• No I do not know mktexlsr Aug 14, 2020 at 17:21
