Mantis2Go is an out of the box installation of MantisBT (a free popular web-based bugtracking system) for Windows.
Maybe the easiest way to try MantisBT on Windows:
1. Start Mantis2Go installer
2. Choose directory where you want to install Mantis2Go (USB stick if you want)
3. Click "Yes" to start Mantis2Go
Simple and to the point. Installation on Windows could not be easier.
