This guide explains how to download, configure and run Retro AIM Server on Windows 10/11.
-
Download Retro AIM Server
Grab the latest Windows release from the Releases page.
Because the Retro AIM Server
.exe
has not been blessed by Microsoft, browsers such as Chrome may think it's a "suspicious" file and block the download, in which case you need to explicitly opt in to downloading the untrusted file.In some cases, Chrome may outright block the download.
While the binaries are 100% safe, you can avoid the security concern by building the application yourself. We do not provide signed binaries because of the undue cost and complexity.
You can alternatively download the file using a Powershell command:
Invoke-WebRequest -Uri "<insert link to version you wish to download here>" -OutFile "retro_aim_server.zip"
and exclude the file or directory from Defender.
Once downloaded, extract the
.zip
archive, which contains the application and a configuration filesettings.bat
. -
Configure Server Address
Open
settings.bat
(right-click,edit in notepad
) and setOSCAR_HOST
to a hostname that AIM clients can connect to. The default setting is127.0.0.1
, which is enough to connect clients on the same PC.In order to connect AIM clients on your LAN (including VMs with bridged networking), you can find the appropriate IP address by running
ipconfig
from the Command Prompt. -
Start the Application
Open
run.cmd
to launch Retro AIM Server.Because Retro AIM Server has not been blessed by Microsoft, Windows will flag the application as a security risk the first time you run it. You'll be presented with a
Microsoft Defender SmartScreen
warning prompt that gives you the option to run the blocked application.To proceed, click
More Options
, thenRun anyway
.While the binaries are 100% safe, you can avoid the security concern by building the application yourself. We do not provide signed binaries because of the undue cost and complexity.
Retro AIM Server will open in a Command Prompt, ready to accept AIM client connections.

Test
To do a quick sanity check, start an AIM client, sign in to the server, and send yourself an instant message. Configure the AIM client to connect to the host set in
OSCAR_HOST
insettings.bat
. (If you didn't change the config, the address is127.0.0.1
.)See the Client Configuration Guide for more detail on setting up the AIM client.
By default, you can enter any screen name and password at the AIM sign-in screen to auto-create an account.
Account auto-creation is meant to be a convenience feature for local development. In a production deployment, you should set
DISABLE_AUTH=false
insettings.bat
to enforce account authentication. User accounts can be created via the Management API.
