I'm having problems downloading a file to a Windows Server 2003 machine. The file is of type .msi. When visiting the page I get the following message:

Internet Explorer cannot download <filename> from <host>.

Internet Explorer was not able to open this Internet site.  The requested site is    either unavailable or cannot be found.  Please try again later.

Here's some details:

  • The file is signed with a certificate I trust.
  • Internet Explorer Enhanced Security Configuration is enabled
  • The site I'm downloading from is added to the list of Trusted sites.
  • In the Internet Options, I've selected the following options under Trusted Sites - Custom Level:
    • Automatic prompting for file downloads: Enable
    • File download: Enable
    • Launching applications and unsafe files: Prompt
  • The site uses https

If I uninstall "Internet Explorer Enhanced Security Configuration", the problem goes away. But I don't want to do this.

Any ideas? Is there some option I've missed?
