My current version is 1.5. There are no more patches to get 1.6. I downloaded all the DLC to see if that would change anything and it didn't. I also uninstalled and re downloaded Empire to see if it would download with any additional patches, it didn't. Do I need to download the Napoleon expansion to upgrade to 1.6? Since the installation instructions stress having version 1.6, I won't attempt to install until I can update from 1.5 to 1.6. Any help would be greatly appreciated. Thank you.
