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:
On Mac, make sure /Library/Internet Plug-Ins/Silverlight.plugin is there. If Silverlight isn’t installed, you can install the latest version from http://www.silverlight.net or http://www.microsoft.com/silverlight.- Do you have administrative privilege on the machine?
You will need local administrative privilege to install Silverlight. - Do you have webshots/kiwee toolbar installed?
There are known issues with Silverlight and old version of Webshots/Kiwee from American Greetings. The fix is to upgrade to their latest version from their web sites. Please see Why do I keep getting prompted to install Silverlight? for details.
- Do you have administrative privilege on the machine?
- Is Silverlight enabled?
For Internet Explorer, select menu item Tools –> Manage Add-ons, make sure Microsoft Silverlight is enabled for all web sites:
For Firefox, select menu item Tools –> Add-ons, click Plugins tab, make sure Silverlight Plug-In is enabled:
- Is the issue site specific?
try http://silverlight.net: 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 http://silverlight.net 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 http://forums.silverlight.net to see whether this is a known issue; and if not, report it.
