    Error "The file appears to use a new format..." with Full version 6 and Reader v9.1

      Hi,


      Environment: XP Pro sp3, Acrobat 6.0, Acrobat Reader 9.1, Internet Explorer 7.0


      Eventhough I have my Reader v.9.1 set up as default application for PDF files in the file association setup, if I click on a PDF link in Internet Explorer, it wants to open it with the full version of Acrobat v6.0 and I get this popup message:


      "The file appears to use a new format that this version of Acrobat does not support.

      It may not open or display correctly. Adobe recommends that you upgrade to the latest version of our Acrobat products…."


      I am puzzled why Internet Explorer ignores the file association setup in Windows Explorer.


      Can someone assist me to figure this out? if the solution involves messing with the registry, or registering/deregistering dll files, that's fine with me.
