If you are using Firefox on Windows, you must add the IP address of the CC-SG to the Allowed Sites for Add-ons list and the Allowed Sites for Pop-ups list in the browser before connecting to a VMW Viewer interface.
If you are using Internet Explorer 10 or 11, you must add CC-SG to the list of Intranet IP addresses before the VMviewer is launched from CC-SG. If this is not done, you may see a message, "Please install the VMware Remote Console Plug-in". The message may display repeatedly even when the plugin is installed. Or, you may see a message "The required VMware Remote Console Plug-in version is not supported by Netscape." Add CC-SG's IP address in the browser under Tools > Internet Options > Security > Local intranet. Click Sites > Advanced, and add the CC-SG IP address to the list. Close all browsers.
The first time you connect to a virtual machine, using any supported browser, you may be asked to download an add-on from VMware. Once the add-on is installed, restart your browser. If the add-on installation fails, see Install VMware Plugins for Firefox 3.0.
