Installation

If your shard doesn't distribute the ClassicUO files, or if you want to use it on a personal shard, the easiest way to install is by using the ClassicUO launcher. The instructions below will guide you though the simple installation process. While the launcher is cross-platform, these directions were written for windows. The steps should be very similar on any OS.

Before running makes sure you have

• Graphics drivers updated to the latest version available
• A x64 bit OS [ClsssicUO does not support x86]
• An Ultima Online installation. ClassicUO does not provide any game asset

Download

• Download the launcher from https://www.classicuo.eu/

• Install latest VC++ redist from here: https://aka.ms/vs/16/release/vc_redist.x64.exe

Installation

• Extract the downloaded ClassicUOLauncher-win-x64-release.zip file into a folder.

• On the Profile tab click Add
  • Give your profile a name

  • Enter the server IP and port number.
  • Enter (or search for) the path to your UO files. These are the actual game files for your server.
