Installing and Running SDL Clipboard Extension for Chrome

Webkit (Google Chrome) doesn't provide system Clipboard access by default, therefore it is not possible for Xopus to copy and paste properly. In order to be able to copy/paste to/from the system clipboard, you need to install the SDL Clipboard Extension.

Here are the few simple steps to install the extension:

1. When you try to copy/paste in Chrome and the SDL Clipboard Extension is not installed yet, it will prompt you to install the extension. A yellow bar will appear at the top. Click Install.

2. The browser will prompt again at the bottom, now click Continue.

3. An Alert will appear, asking to install the SDL Clipboard Extension. Click Install.

4. Make sure you save your work before the following step.

5. Reload the browser and you should now be able to copy and paste in Xopus in Chrome.

Server Configuration

Please note that some servers will server a HTTP 404 error message for files for which they do not know the MIME type. In this case you will need to add the MIME type to the server settings. The server will then server the file properly.

In IIS go to your website properties->HTTP Handlers->MIME-TYPES->Add MIME type. You should see the following dialog, and fill it out as shown.

As you can see above, the extension of the Chrome extension is crx, and the MIME-TYPE (which is used by the browser to understand what to do with the file) should be application/x-chrome-extension. This setting is not a client setting, and will only be have to set once for your implementation.
