Google Chrome browser

Since September 2nd, 2015, the Microsoft Silverlight plugin which is used in order to use Sieval Deco is no longer supported by the Google Chrome browser. Ultimately, Sieval Deco will become independent of this plugin and Chrome can be used again. Until then, we advise you to open Sieval Deco in another browser, for instance Internet Explorer or Mozilla FireFox. Both can be downloaded for free via the internet (click the link).
