Symptoms
For Chrome, the Downloads page is under the Window drop-down in the upper left corner of your browser. Right-click or hold Control on your keyboard and select Silverlight.pkg. Select Open on the pop-up menu. Select Open on the prompt that says Silverlight.pkg is not from the Mac App Store. Silverlight offers a flexible programming model that supports AJAX, VB, C#, Python, and Ruby, and integrates with existing Web applications. Advertisement It supports fast, cost-effective delivery of high-quality video to all major browsers running on Mac OS or Windows OS. RECOMMENDED: Use Silverlight in the 32-bit Internet Explorer process on x64 systems. Most browser plug-ins (including Silverlight, Flash, Java and almost all ActiveX controls) only work in 32-bit browsers currently.
When you use Google Chrome (version 42.0 or later) to access a website that runs Microsoft Silverlight, you see that some content is missing or that the Install Microsoft Silverlight badge is displayed. When you reinstall Silverlight, the issue still occurs.
Note This issue does not occur in Microsoft Internet Explorer, Mozilla Firefox, or Apple Safari. These browsers still support Silverlight content.
Cause
Use Silverlight On Mac
This issue occurs because these versions of Chrome block Netscape Plugin API (NPAPI) plugins from being displayed in the browser. Silverlight is an NPAPI plugin.
Workaround
On Chrome version 45 or a later version of Chrome, there is no workaround for this issue. You must use a browser that supports Silverlight content to access a Silverlight page.
To work around this issue on versions 42 to 44 of Chrome, follow these steps:
On the address bar in Chrome, type chrome://flags/#enable-npapi.
In the Enable NPAPI Mac, Windows box, click Enable.
Exit and then restart Chrome.
Reopen the Silverlight page.
Right-click the broken puzzle piece image, and then select Run this Plugin.
