What's happening...
After working of more than a year, Google is finally ready to end the official support for NPAPI and block the relevant plugins like Microsoft's Silverlight, Oracle’s Java and many more. The company has been working on removing NPAPI support since 2013 and finally the latest update comes with a new API.
Chrome 42 supports PPAPI, a new API and hence the incompatible extensions and plugins are blocked by default. NPAPI is an old and obsolete API and often leads to plugin crash/hang and other security incidents, hence Google decided discarding it in its latest web browser update.
Any content requiring NPAPI will not load on Chrome 42 and there won’t be any error messages either. But if you are using those plugins via the web browser, you might get a prompt to install a relevant plugin.
What it means...
For RealTime, the web page assumes that Silverlight is not installed and requests that the user re-install it.
How to solve it...
Existing users can however, still use those plugins by re-enabling them directly in their web browser. Just type (or Copy/Paste) Chrome://flags on the address bar, press Enter then scroll down and locate NPAPI settings and click on enable. Restart the browser and you can use those plugins.
The Future...
Google intends to completely disable the support later this year. Users can use the NPAPI based plugins till then.
