Configuring Client Browsers to Accept the RTC ActiveX Control

Portal users that want to use the RTC application sharing tool need to have the RTC ActiveX control on their system.

The system administrator needs to make sure that the browser security settings of each user are appropriately configured so that they can accept the ActiveX control. Browsers can be configured to accept ActiveX controls either with or without the user's confirmation. We recommend the former configuration to protect user's systems from unsolicited and harmful ActiveX installations.

This topic describes how to configure a browser's security settings so that it can accept ActiveX controls. Alternatively, your IT department may use other appropriate methods to deliver the necessary ActiveX control to the client machines.

 

The user logged onto the machine to which the ActiveX control needs to be installed must be defined as a Windows administrator.

 

1. In Microsoft Internet Explorer, from the Tools menu, choose Internet Options.
2. Choose the Security tab.
3. Choose either the Internet or Local Intranet icon (depending on the zone providing access to your organization's portal).
4. Choose Custom Level.
5. Under ActiveX controls and plug-ins → Download signed ActiveX controls, choose one of the following:
   • Prompt: To be prompted before ActiveX controls are installed on your system. (Recommended)
   • Enable: To allow ActiveX controls to be installed on your system automatically without your prior consent.
6. Under Run ActiveX controls and plug-ins, choose either Enable or Prompt.
7. Choose OK to close the Security Settings window.
8. Choose OK to close the Internet Options window.

 

To determine if the RTC ActiveX control has been installed on a user's system, note the following:

• If a user initiates an application sharing session, and the first dialog displays the list of applications currently active on his or her desktop, then the control has been downloaded.
• If a user has been invited to participate in a sharing session, and can see the host's shared application on his or her desktop, then the control has been downloaded.

You can also verify the download as follows:

1. In the Web browser of the user, from the Tools menu, select Internet Options.
2. In the General tab, click the Settings button.
3. In the Settings window, click the View Objects button.
4. In the Download Program Files window, if any of the following appear in the Program Files list, then the ActiveX control was downloaded:
   • ExpBaseNegotiator
   • ExpApplSelect
   • ExpApplShareX
