Moonlight 4 out-of-browser

I'm trying to launch some of my开发者_开发百科 existing Silverlight apps out-of-browser on Ubuntu and Moonlight 4 Preview. Install the apps was pretty sweet using Firefox and Chrome.

I received the same error message for all samples I tried:

Fails to execute child process

"...some long

path.../moonlight/lunar-launcher"

(Permission denied)

Any one has a tip?

It looks like either the 'lunar-launcher' app doesn't have execute permissions (run chmod +x /home/lenovo/.mozilla/firefox/x9y2ruwx.default/extensions/moonlight@novell.com/plugins/moonlight/lunar-launcher to fix it) or else the directory it is contained in doesn't have the correct permissions (try chmod +rx /home/lenovo/.mozilla/firefox/x9y2ruwx.default/extensions/moonlight@novell.com/plugins/moonlight to fix)
