How do I install packages on MiKTeX or TeX Live on Windows?
Answer
If you get a "file was not found" error for a class file or package, it needs manually installed. Most class and package files are at ctan.org.
When you use MiKTeX, find where the tex and bibtex folders are. Install the bst files in the bibtex/bst folder. All of the other files that are not documentation files or tex files are installed in the tex/latex folder. Usually, I create a folder for the package in these folders to be more organized. After copying the the files, run the texhash command to complete the install.
The installing packages webpage will give you possible directories. A demonstration videos about installing packages when you are using MiKTeX is on the webpage as well.
