The installation procedure is explained in the first tutorial, available at https://spoken-tutorial.org/watch/LaTeX/LaTeX+on+Windows+using+TeXworks/English/, at 4:56 minutes onwards.

If you follow the method explained in the tutorial that I mentioned above, it will install ALL missing packages. If some package is not found, it means that all packages did not get installed, for some reason or other: not having Internet access could be one reason, for example.
I will now suggest a less elegant solution (you should actually try the method explained in the tutorial): search for the missing file (in your case, pdfescape.sty) and download it. Move it to the current directory. Similarly, download "All" missing files, and move them to the current directory. The program should compile now. But you can see that this is not at all elegant. You need to keep all the missing files in every directory.
