Sigma installation and registration

  • The WarpIN package manager is required to install Sigma, if your OS/2-based system does not recognize files with the WPI file extension. (ArcaOS includes a compatible version of WarpIN, and does not require a separate download.)
  • To register your Sigma license, from the main menu, select Options -> Register and enter your registration name and code without any additional spaces. After correctly entering your registration information, you will be presented with confirmation of your valid registration.
