Short answer: this is a platform/security difference, not a bug in your script. On Vista Internet Explorer runs with User Account Control and a Protected Mode (low-integrity) sandbox that prevents web pages in higher-risk zones from instantiating COM objects that access the local file system. That is why behavior that could be changed on XP by adjusting browser security no longer works the same way on Vista.

Safe, practical options:

  • Run the logic outside the browser (an HTA or a .vbs executed by Windows Script Host) so it runs with normal desktop privileges.
  • If this must be a browser solution inside a controlled environment, deliver a signed, installable client component (ActiveX or native helper) and deploy it via Group Policy to the machines that need it.
  • For short-term testing only, running IE elevated or hosting the page in a lower-security zone will change the result, but do not leave those changes enabled for normal browsing.

Quick troubleshooting checklist:

  • Confirm Protected Mode and UAC are the limiting factor by running the same HTML as an HTA or via WSH; if it works there, the browser sandbox is the cause.
  • On 64-bit Vista, check the bitness: a 32-bit COM object will fail if IE is running 64-bit.
  • Verify the COM object is properly registered for the bitness you are testing.
  • Avoid permanently loosening Internet-zone ActiveX settings; that creates a major security risk.

This ties back to what , and observed: the fix that worked on XP (changing browser security) is ineffective on Vista because of the design changes in the browser/OS security model.
