I spent hours trying to resolve this. I installed Miktex, but was unable to get the packages directly from the package manager due to sitting behind a firewall at work. I finally was able to resolve this using the following steps:

1. Install Miktex
2. Create a folder to install Miktex packages, eg "C:\\miktex_pkgs"
3. Go to the CTAN package archive and download the following .tar.lzma files:

-fancyvrb
-framed
-microtype
-miktex-zzdb1-2.9
-miktex-zzdb2-2.9
-mptopdf
-titling
-upquote
-url

4. Move the above .tar.lzma files to the "C:\\miktex_pkgs" folder

5. Set your packages to download from the local repository: "C:\\miktex_pkgs". To do this, go to:

   • "Miktex Settings" - this is an application
   • Click Packages
   • Change Package Repository to "C:\\miktex_pkgs"

6. Go to "Miktex Package Manager" application and install the following packages by right-click, install:

   • List item
   • fancyvrb
   • framed
   • microtype
   • mptopdf
   • titling
   • upquote
   • url
