Detect if Silverlight is installed from c#

I am creating an MSI for installing my Silverlight OOB application. It should install Silverlight Plugin if it is not present, or the required version is not present.

So, how can I detect if Silverlight exists on my machine. If present how can I know which version is present.

My MSI is distributed, may not be downloaded from webpage, so I can't put any javascript and download the MSI package accordingly.
