    FYI (just getting the warning out)

    NPAPI ("Netscape Plugin API") was disabled today with an update to Chrome v42.

    To enable, follow this link in Chrome: chrome://flags/#enable-npapi

    *Click enable*

    Close all instances of Chrome (tabs & windows) and restart Chrome. Chrome should continue to work with Silverlight until around September when NPAPI support will be removed. See link for more info:

    Push users to IE or another browser or go full OOB to continue support. Hope this helps.

    Good luck,

    Hi Patrick,

    Thanks for sharing this information with the community.

    I just wanted to make a quick note that restarting the browser appears to not work every time. However, when pressing Enable for the NPAPI, a small button on the bottom of the browser "Relaunch now" appears that seems to work flawlessly.

    Thanks Petya, that does work better.


    Also a quick note on alternatives for hosting a Silverlight application beyond using other browsers or OOB: MSDN Alternative Hosting 


    Thank you,
