Shared model packages and projects are stored on Horizzon. If you are working with a locally installed Enterprise Studio, you need to connect Horizzon to your Enterprise Studio before you can start working on model packages and projects. 

Usually, if you have registered with Horizzon, you also have already connected Horizzon with Enterprise Studio. However, if you have received a Horizzon account via an identity provider in your organization (for example an Azure AD account), you still need to connect Horizzon to your local Enterprise Studio.

It is also possible that you need to add a second Horizzon or connect Horizzon again after it has been removed from Enterprise Studio.

The following ways are available to add a storage place (Horizzon) to Enterprise Studio:

• Download the Horizzon configuration file (.jssc) in Horizzon, and drag the file onto the open Enterprise Studio application window.
• Add the storage place via the Open menu in the Backstage view.
• Add the storage place via the Enterprise Studio Options.
• Add the storage via the Save As menu in the Backstage view (only for second and further storage places).

Steps:

1. Choose a starting point:

    Download the Horizzon configuration file and add it to Enterprise Studio

   1. In Horizzon, click your profile icon, and then click Download configuration for Enterprise Studio. Store the configuration file (*.jssc) somewhere local on your computer where you can easily access it.
      
      
      
      
   2. Open your Enterprise Studio. The following message appears. Click OK to close it.
      
      
      
      
   3. Drag the previously downloaded configuration file onto the application window, and release the mouse button when the mouse pointer turns into .
      
      
    The Open menu

   1. Go to File > Open, and then click Add storage place.
    The Enterprise Studio Options

   1. Go to File > Options.
      
      
   2. In the Enterprise Studio Options window, click Storage places, and then click Add.
    The Save As menu

   1. Go to File > Save as, and then click Add storage place.
2. In the Add Storage Place wizard that appears, in Server, add the URL of your Horizzon environment. If you have added the configuration file to Enterprise Studio, the URL is automatically filled.
   
   
   
   Accept all server certificates: If HTTPS is used to connect to Horizzon, this check box is available. If you select it, checking on certificates is relaxed, meaning that one could possibly communicate with an imposter Horizzon. Leave the check box blank if you do not want this. If you are not sure what to do, consult your application manager.
   
   Proxy settings: If you are using a proxy server, it will automatically be detected when adding the storage place, and used for the connection between Enterprise Studio and Horizzon. However, if automatic detection does not work in your situation (for example due to security reasons), you can manually specify the proxy settings here. For more information, see Using a proxy for the storage place connection. If you are not sure what to do, consult your application manager.
   
   
3. Click Next to continue, and on the next page of the wizard, click Finish.
   
   
    
   
4. A pop-up window of the Activity Console appears, in which you need to authenticate. How you sign in depends on your type of Horizzon account. The sign-in window will look accordingly. An example:
   
   
   
   Signing in with Horizzon credentials
   Enter your Horizzon credentials in the appropriate boxes, and then click Sign in. In case there is also the option to sign in with an organizational account, then first click Use a different account, and then enter your Horizzon credentials.
   
   Signing in with Windows, Azure AD or another organizational account
   

5. Click the Sign in with '<name>' button.
   
   If the Sign in with Windows button is not available when signing in with Windows, or if you are signing in with Windows from outside the domain or as a different user, enter your Windows credentials in the appropriate boxes, and then click Sign in.
   

Horizzon is now available as a storage place in Enterprise Studio. Model packages and projects you have been invited to, are available on this location. You can open them and start working on them.
