In 2015, Chrome doesn't support silverlight anymore. So my app can't run on Chrome, but Firefox,... is run normally. Silverlight can be run Out-Of browser, but it happen when we can access to the page, right click and install out of browser. But now Chrome doesn't let me access to silverlight.

So how to solve this problem?

  1. I notice to my users use another browser like firefox, opera,....
  2. ????

Your clients need to enable the NPAPI manually in chrome. It is now deactivated by default. This can be done by using 

chrome://flags/#enable-npapi

in the address bar of chrome.

Here is a link to a walktrough to activate it.

UPDATE:

Since Chrome 45 NPAPI is completly gone from Chrome, but there seem to be workarounds. (See also With Silverlight disappearing from Chrome 45, what are my alternatives?)

UPDATE: The answer below is valid for Chrome versions 42-44 only. Please refer to the Jehof's answer above for a workaround in versions 45+.

Since version 42, Chrome blocks Netscape Plugin API (NPAPI) plugins from being displayed in the browser. See KB 30582554 for details.

To work around this issue:

  1. On the address bar in Chrome, type chrome://flags/#enable-npapi.
  2. In the Enable NPAPI Mac, Windows box, click Enable.
  3. Exit and then restart Chrome.
  4. Open the Silverlight page to check.
  5. Right-click the broken puzzle piece image, and then select Run this Plugin.
