Another limitation of the isSilverlightInstalled function is that it is non-portable.

What if the user has a Silverlight plugin installed but is running another browser than Internet Explorer, Firefox, or Safari? Lets speculate that the user is running a browser that doesn't have the navigator.plugins object or the ActiveXObject class, then isSilverlightInstalled will return false, even though the plugin is installed. The chances for this is rather slim, but still the test is non-portable.

Depending on how the isSilverlightInstalled function will be used, it may or may not matter. If the function is only used for calling the Auto Start method it shouldn't matter.
