All old PDF files in our websites are not opening from the desktop nor via IE or Chrome browser.  I am using the latest Acrobat Reader DC version 19.2560.

Note: The new pdfs are opening without any issue.

Here is the error message...

on desktop:

on Chrome:

on IE:

    When it starts with

    <?hda jcharset="UTF8" encoding="utf-8"?>

    it is not a PDF file.

    Also the after updating the browser versions, i am able to open the pdfs in the browser.

    What can you see at the first lines when you open one of the files in Notepad?

    files start with:

    <?hda jcharset="UTF8" encoding="utf-8"?>
