Disabling Silverlight addon in IE9 is not such a good idea
The other day I disabled Silverlight add-on in IE9. Don’t ask me why I don’t really remember, and I prefer not.
Then I uninstalled it and reinstalled it! Same issue.
It took me time to remember that I disabled the Silverlight add-on in IE9 and for sure when I enabled it, then the out of browser applications were working again and I didn’t get anymore this install Silverlight picture.
