Silverlight Deployment Troubleshooting Guide

After helping a few customers with Silverlight install issues, I think it may be helpful to publish a Silverlight deployment troubleshooting guide and keep it up-to-date, so here you go.

Troubleshooting Steps

  • Is Silverlight installed?
    on Windows, make sure “Microsoft Silverlight” is in Control Panel –> Programs and Features:
    check Silverlight in appwiz.cpl
    On Mac, make sure /Library/Internet Plug-Ins/Silverlight.plugin is there. If Silverlight isn’t installed, you can install the latest version from or
  • Is Silverlight enabled?
    For Internet Explorer, select menu item Tools –> Manage Add-ons, make sure Microsoft Silverlight is enabled for all web sites:
    Make sure Silverlight is enabled with IE For Firefox, select menu item Tools –> Add-ons, click Plugins tab, make sure Silverlight Plug-In is enabled:
    Make sure Silverlight is enabled with Firefox
  • Is the issue site specific?
    try if you see the showcase Silverlight application on the top right of the page, then your issue is likely to be site specific, please report the issue to the site owner. O/w, please click the Forums tab at page, search and/or report the issue there.  
  • Is the issue browser specific?
    try open the page in a different browser (IE/Firefox/Chrome on Windows, Safari/Firefox/Chrome on Mac) and see whether the issue repros. If it doesn’t repro, it is likely to be a browser specific configuration issue. Again, it may help to search to see whether this is a known issue; and if not, report it.

This is first version, I will keep adding content to the post and keep it up to date with issues I see reported. Thanks!
