The Microsoft Actor Properties Viewer + Decompiler (MAPVD) is a freeware properties viewer software developed by Konnor88 that displays the properties of a selected Microsoft Actor character. The program can display the animations count, description, frame count, version, and sounds of most Microsoft Actor 1.0 and 2.0 characters.
Usage
The program features an "Open ACT..." button that can be used to select an .ACT file. Once an .ACT file is loaded, a user will be able to see all the available details of the Microsoft Actor character, with the program automatically decompiling all frames and sounds in the same directory the Actor was selected in.

Properties
The following properties are available in the property viewer:
- Description - Shows the character description. Currently, the property viewer can only view this for Microsoft Actor 2.0 characters.
- Name - The internal name of the Microsoft Actor.
- Version - Displays the version of the Microsoft Actor file, 0x0001 for 1.00 and 0x0002 for 2.00.
- Frames - The number of frames the Microsoft Actor has.
- Animations - The number of animations the Microsoft Actor has.
- Frame - Shows a preview of the selected frame from the combobox. All frames are auto-extracted to the same directory as the .ACT file.
- WAV - Shows a preview of the selected WAV from the combobox. All WAVs are auto-extracted to the same directory as the .ACT file.
Trivia
- The reason it cannot render the characters directly like the Microsoft Agent Properties Viewer can with Microsoft Agent characters is because Microsoft Actor does not have an official public programming API, while Microsoft Agent does.
- The release of MAPVD represents the first documented and publicly available tool capable of successfully decompiling a Microsoft Actor character. Prior to this program, no complete decompilation method for .ACT files had been published.
- MAPVD identifies and extracts Vector-based Windows Metafile (WMF) artwork used by Microsoft Actor, a notable distinction from the bitmap-based 256-color image pipeline used by later Microsoft Agent (.ACS) files.
- As the Microsoft Actor format is still actively being studied, the amount of properties displayed is currently limited.
