Installing OpenWebStart to run the Coeus Premium Application

Authors list

Members of the Brown Community who need to use Coeus Premium should connect to Coeus using the OpenWebStart (OWS) version of the Java application. OpenWebStart takes a Java connector to a Coeus helper file (in JNLP format), and launches a Coeus Premium session for you.

Mac and Windows computers that have OIT's management tools can easily install the OWS application and use a shortcut or download a JNLP file. If you are on an unmanaged computer, or the OWS application is not available to your managed machine, the OWS application is straightforward to download and then connect to Coeus.

Coeus Premium is also available as a shortcut in the start menu of Brown's MyApps service



Windows Computers with Brown Management

Many departments' management profiles include the OpenWebStart plus Coeus shortcut for installation from the Software Center console.  

To initiate an installation:

1.  From your start menu, search for "Software Center" and launch the application.

2.  Go to the Applications tab, and look for COEUS - OpenWebStart. Click the icon to get to the install link.

3.  Click "Install" to initiate the process. You do not need to be on campus or VPN for this.


4.  Upon completion, the OWS Java application will be installed in the background, and you will have a "Coeus Shortcut" on your desktop.

5.  Double-click the "Coeus Shortcut" to launch Coeus Premium. The first time you run the shortcut, Java components will be installed in the background, and you may be prompted to "Always trust content from this publisher", please Click "Run" to approve this prompt.

6.  You may be prompted to "Add shortcut to desktop" and you would click "OK".


7.  An additional Coeus shortcut will be placed on your desktop. Both shortcuts will be functional after completion.

Troubleshooting

After installation on a Mac, you may need to set permissions for OpenWebStart to access your file system. On newer Macs, some functions, such as upload of files, may require this for full functionality. If you encounter this problem, go to System Preferences -> Privacy & Security, then choose Full Disk Access, and change the slider to allow "Full Disk Access" for OpenWebStart.
