Does Silverlight 4 launch a trusted application in a browser?

I just lost 5 hours to find an answer that I could not find: p

First, I would like to force a trusted application (I need to access the file system) to display in the browser. Based on what I found in google, a trusted application should be installed and running as a desktop application (also called a non-browser application).

So, I want to have the application installed on the client side, but for now, the user should also run the same application in the browser window when he goes to my website. Is it possible?

Secondly, I would like to give the user the opportunity to run the application from a browser. To be clear, the application is installed on the client computer, but I want a button on my website that launches the desktop application. How can i do this?

thanks

The answers seem to be no.

Yes, you can run the application installed on the client also in the browser. However, not all installed application features will be available. Anything that requires increased trust will not work in the browser.

No, you cannot run an installed application programmatically from code running in a browser. The best thing you can do is to show a polite message to the user that he already has this application installed, and in order to gain access to all his functions, he will need to run it.
