Why does some local content, such as an instructional CD-ROM, not work properly in Internet Explorer?

Internet Explorer blocks active content, such as that on some instructional CD-ROMS, by default.

Files opened by Internet Explorer in the Local Machine zone are subject to new Local Machine Lockdown settings. This restricts the settings to prevent malicious code execution from gaining access to objects located on your computer. When other applications host HTML, they are automatically exempted from the new Local Machine zone settings.

Symptoms of a failure related to this change appear on the Internet Explorer Information Bar, providing notification that content was not loaded due to the security settings in place. One example of this would be for CD-ROM content that utilizes HTML and scripting for interactive content or other actions.

Method 2:

  1. In Internet Explorer, from the Tools menu, click Internet Options.

  2. In the Internet Options dialog box, click the Advanced tab, and then scroll down to the Security section.

  3. The Allow active content from CD's to run on My Computer and Allow active content to run in files on My Computer check boxes provide the ability to disable the Local Machine restrictions for CD-ROM content or for local drives, respectively.

    Note: The Allow active content from CD's to run on My Computer and Allow active content to run in files on My Computer options were enabled to enhance security in Internet Explorer. Disabling them should only be used as a last resort.
