Desktop Computers

Silverlight requires an x86 processor with Streaming SIMD Extensions (SSE) support. Supported processors include the Intel Pentium III and up, and the AMD Athlon XP and up. Newer AMD Duron models are also supported.

The following table presents an availability and compatibility matrix of Silverlight versions for various operating systems and web browsers.

An upcoming Opera support was promised since May 3, 2007, when David Storey, the Chief Web Opener at Opera, revealed a Microsoft poster for MIX conference that had shown Opera integration as a part of Silverlight 1.1. As of December 2011, however, Silverlight still does not officially support Opera. Silverlight 1.0 could be made to work with Opera via a hack. Starting from Silverlight 2, hacks were no longer required.

On Linux and FreeBSD, the functionality is available via Moonlight. Moonlight is available for the major Linux distributions, with support for Firefox, Konqueror, and Opera browsers, provided it was obtained through Novell. Miguel de Icaza has expressed an interest in working with developers from other operating systems (BSD, Solaris) and other browsers (Konqueror, WebKit and Opera) to ensure that Moonlight works fine on their systems. Availability of Moonlight version 1.0 for FreeBSD was announced in March 2009, but has since been reported not to actually work. As of 2011 the current version of Moonlight (4 Preview 1) does not officially work on new versions of Firefox (newer than 3.x) on GNU/Linux-based operating systems. However, it can be installed in an unofficial way (for example using the Add-on Compatibility Reporter add-on) and with Firefox 11 it works correctly when installed. As noted above, the Moonlight project was abandoned in May 2012.
