Below are the setup instructions for installing Microsoft Agent manually.

Microsoft Agent is not an application that you can just run like Word or any other program and expect to have characters do things for you automatically.
Websites and Applications must be specifically programmed to use Microsoft Agent and provide these characters for you.

Additional information and documentation can be found on the Microsoft Agent Home Page.

 STEP 1 (Required)

Download Install Microsoft Agent Core Components
version 2.0 (395K)

Note WINDOWS XP/2000/Me Users may skip this step.  The Microsoft Agent Core Components are already installed on Windows XP, Windows 2000, and Windows Me.
 Make Agents Speak!
Microsoft Agent uses SAPI 4.0 to have it's agents speak. However, now, Windows XP is shipped with SAPI 5.0 which is not compatible with this, so your agents cannot speak. Thankfully, both SAPI 4.0 and 5.0 can be on your computer at the same time with no problems, so download (spchapi.exe) SAPI 4.0 from Microsoft and then follow the next instructions.

Download the above MSAgent.exe setup program and run it to install the core components. 
You may then delete the setup program.


Download Install the Lernout & Hauspie TruVoice,
Text-to-Speech Engine (English version)  (1MB).

The Lernout & Hauspie TruVoice Text-to-Speech (TTS) Engine provides speech output capabilities for Microsoft Agent so you can hear what the characters are saying through your sound speakers.

Download the above tv_enua.exe setup program and run it to install the TTS Engine.  You may then delete the setup program.

If you've already installed this, you should see
Lernout & Hauspie TruVoice American English TTS Engine
in the Control Panel's Add/Remove Programs list.

Additional Lernout & Hauspie TTS3000 Engines may be downloaded from the table below.  You need to download and install both the TTS Engine and the Language Add-On for the desired Language.

For example, to install French Text-to-Speech, download and install both lhttsfrf.exe and agtx040C.exe

Microsoft TTS Engines

Mary - Female Voice (English) 2.3MB

Mike - Male Voice (English) 2.4MB

Sam - Male Voice (English) 2.1MB

Microsoft Agent can utilize TTS Engines from many other speech vendors, including versions of ATT Natural Voices, Digalo, Elan Speech, IBM ViaVoice, and more.  The only requirement is that the TTS Engine is SAPI 4.0 compatible.  SAPI 5.0 is not currently supported.


Download Install the Microsoft Speech Recognition Engine,
version 4.0 (6MB)

This step is optional.  You can download this later.

The Microsoft Speech Recognition Engine provides speech input capabilities for Microsoft Agent. This allows you to speak to characters through a microphone.  However, Microsoft Agent must be specifically programmed to understand and interact with what you are saying.  Microsoft Agent does not support dictation.

Download the above actcnc.exe setup program and run it to install the TTS Engine.  You may then delete the setup program.

If you've already installed this, you will see
Microsoft Agent Speech Recognition Engine 4.0 (English)
in the Control Panel's Add/Remove Programs list.


Download Install the Microsoft Speech Control Panel

This step is optional.  You can download this later.

The Speech Control Panel will add an icon to your Control Panel to enable you to list the compatible speech recognition and text-to-speech engines installed on your system and customize their settings for your use.


Download Download some Microsoft Agent Characters

Rainbow Arch uses the four Ms Agents Merlin, Genie, Peedy & Robby

There are many Agent characters available and many more are being created.  Now that you have Microsoft Agent installed on your computer, you only have to download additional Characters
(files with .ACS extensions) as they become available and save them to your computer
depending on your operating system.
