Enabling Java Runtime Environment (JRE) in Chrome 42

This applies to SciFinder®, New STN®, and STN® on the WebSM.

On April 14, 2015, an update to Google Chrome disabled browser support of NPAPI by default. This blocks the Java Runtime Environment (JRE), which is required for the Java-based structure drawing editors of SciFinder, New STN, and STN on the Web to function.

Below are instructions for enabling NPAPI support to allow the JRE plugin to run. This applies to both Windows and Apple operating systems running Google Chrome.

1.  Open Chrome and type the following in the address bar:  chrome://flags#enable-npapi


2.  Click “Enable” to restore NPAPI functionality.


Note: Above  “Disable” view is shown after enabling.  Clicking again will reset NPAPI to the default disabled state.

3.   Scroll to the bottom of the page and click “Relaunch Now” to save your change.


4.  Java should now work in Chrome.  Your browser may prompt you to allow plugins, especially if you also updated Java and accepted the “Reset Security Prompts” default. The example below is from Apple OS X 10.10 (Yosemite).


Selecting "Always allow..." is the recommended option for CAS products.
