Thank you for your interest in Regisfall. Before playing, it is highly recommended that you read the rules.


1. To get started on Regisfall, first download and install the Regisfall Installer, Patcher, Launcher ("IPL")
Note: Some web browsers may detect this file as being malicious. If you are unable to download the IPL, attempt to copy/paste the link into a new browser tab.

2. Select your install location and proceed with installation; the default location is "Program Files/Regisfall". Once installed, you may click the UO icon to load the ClassicUO client.

Note: This installation comes pre-loaded with the Razor assistant tool.

3. You may now log in using your desired username and password.


1. If you do not wish to install using the Regisfall IPL above, first download and install Ultima Online.

Important note: The default install path name("Ultima Online Mondain's Legacy") can cause Classic UO to throw an error message due to the apostrophe in the name. It is recommended to create a directory name without any special characters.

2. Download the Regisfall file package (last updated 30 June 2024) and unzip it into your UO directory

IF UPDATING FILES: Do NOT overwrite settings.json as it stores your login preferences.

3. The Classic UO Client is recommended for playing on Regisfall. A customized version of this client is included in the Regisfall package, named Regisfall.exe. Alternatively, you may use the standard client or any game launcher such as Razor or UO Steam.

- Load the Regisfall Client from (your Ultima Online install directory)/Regisfall.exe
(You can right-click to create a shortcut, and move it to your desktop for easier access)

4. You may now log in using your desired username and password.
