Otimize Nesting was developed based in Microsoft Silverlight technology.
Applications written in this technology requires the Silverlight plugin to be installed in the browser in order to run.
Unfortunately new browsers do not support any plugins. Therefore Silverlight will ends its support soon.
The only remaining web browser that still supports it is Internet Explorer on a Windows-based PC for that.
We still have not decided if a new version will be available as a web application (cross platform) or a native app (for Windows and possibly MacOS).
