Begin Your Journey

Step 01

Get the UO Classic Client Files

Ultima Online requires the original game data files. Download the free Classic Client from the official Ultima Online website (uo.com). Install it to get the data files — you don't need to launch the official client after that.

The data folder you need is typically: C:\Program Files (x86)\Electronic Arts\Ultima Online Classic

Step 02

Download the ClassicUO Launcher

ClassicUO is the open-source client used to connect to Immortal Realm. The easiest way to install and update it is via the official ClassicUO Launcher from classicuo.eu.

Download the Windows installer and run it. The launcher installs to a folder of your choice — note where you put it; ClassicUO itself will be downloaded into <classicuolauncher_folder>\ClassicUO\ on first run.

Step 03

First Run — Let It Download ClassicUO

Open the ClassicUO Launcher you just installed. On its first run it will download the ClassicUO client files automatically — you'll see a progress bar. Wait for it to finish before continuing.

The downloaded client files land in <classicuolauncher_folder>\ClassicUO\. You don't need to do anything with that folder directly; the launcher manages it.

Step 04

Create an Immortal Realm Profile

In the launcher, click Edit Profiles (or, on a brand-new install, the big Create your first profile! button). On the Profile tab click Add and fill in the fields below — the values for our shard are listed afterward.

• Profile name — anything you like, e.g. "Immortal Realm".
• Username / Password — optional. Fill these in if you'd like the launcher to save them; otherwise leave blank and you'll be prompted at login.
• Server IP and Port — the shard's connection details (see below).
• Path to your UO files — the folder from Step 01 where the Classic Client data lives.
• Client version — usually auto-completed. If not, set it manually (see below).

Step 05

Launch & Create Your Account

Save the profile, click Play, and log in. Enter a username and password on the login screen — this creates your account on the shard directly, no website registration required. Once logged in, create your first character and begin your story in New Haven.
