The Microsoft Agent Decompiler (MAD) is a freeware decompiler software developed by Lebeau Software that allows users to decompile Microsoft Agent 2.0 characters. It was available for download on the Lebeau Software website.[1]
Usage
The program can be used to decompile Microsoft Agent characters. It can also be used to give Office Assistants and desktop assistants voices and to get the images for the character articles that lack them. In order for a character to be decompiled, they must be a 2.0 Microsoft Agent and must not exceed 256 pixels in size. Originally, it was used for when the creator developing the Microsoft Agent character loses the ACD file. It also used to be illegal to decompile Microsoft's own Microsoft Agent characters despite Microsoft Agent being discontinued in 2009.
As of 2026, with the discontinuation of Microsoft Agent in 2009, it is relatively risk-free to decompile Microsoft's own Microsoft Agent characters.

Trivia
- It is unknown what programming language the Microsoft Agent Decompiler was written in.
- It was used to decompile almost every Microsoft Agent character.
- Microsoft Agent 1.5 characters were unable to be decompiled with the Microsoft Agent Decompiler due to 1.5 characters being compiled differently from 2.0 characters.
- However, in 2025, a proof-of-concept decompiler for uncompressed Microsoft Agent 1.5 files was developed and made available on TMAFE.COM, with the source code published on GitHub.[2]
- The maximum pixels in size that a Microsoft Agent character can be decompiled is 256 pixels. Exceeding this limit causes an error saying "Destination buffer exceeded", but the audio is still decompiled.
- It is likely that the Microsoft Agent Decompiler has been discontinued by Lebeau Software.
