Okay, stupid question but I haven't found out anything about this:How do you know if Silverlight is actually installed on a computer which tries to display your Silverlight app? If Silverlight is not installed yet, how can you show an error page / download link?
Thanks

This should do it, only a few lines of code

One thing you can also easily do is check in Internet Explorer to seeif Silverlight is installed:
Tools'->Managed add-on
If Silverlight is installed then it should be displayed under
Name Publisher Status Version ------------------------------------------------------------------------------------------------------Microsoft CorporationMicrosoft Silverlight Microsoft Corporation Enabled 3.0.40818.0 <------
Now a simple test you can do is simply change the Status to Disabled...Then reload the same page in your browser to see what's happening...Basically, your browser won't be able to recognize any Silverlight code...So what will it do? Simply skip the SLV code part and jump to the next line of codeit can recognize and is able to render...By default you should end up with a Silverlight logo on the top left of your screen... But of course you're free to make any other modification you want...-add a gentle notice to the user that it's time to upgrade, FREE BEER ON LINE!!!! :) -redirect them to Silverlight.net ... -at the most... even add a "good old sniffer" function to check if Javascript is enabled on the client's browser... etc... etc... etc...
If this answers your question please click Mark as an answer, Thank you.
