Hello,
What OS are you running?
In your case, Services are not allowed to interact with the desktop in recent versions of Windows. Windows cannot be configured to behave differently in this situation. If the installation program is run as a logged-in user, the progress bar / interactive prompts display normally.
• Interactive - Users interact with all installation dialog boxes.
Note: If you use this setting, be aware that users are free to select a custom client software installation, and then install different components. This option is not supported for Microsoft Vista because of Vista security features. If you use this option and try to install software on the computers that run Microsoft Vista, your installation fails.
• Unattended - Users do not interact with installation screens, but see a Windows progress dialog box only.
Unattended is the default setting.
Note: This option is not supported for Microsoft Vista because of Vista security features. If you use this option and try to install software on the computers that run Microsoft Vista, your installation fails.
• Silent - Users do not interact or see the installation dialog boxes.
Note: You must use this option to successfully install the client software on the computers that run Microsoft Vista because of Vista security features.
Note: When a silent deployment is used, the applications that plug into Symantec Endpoint Protection, such as Microsoft Outlook and Lotus Notes, must be restarted.
Hope that helps!!
