    You may need to make a little change to the Windows registry: download, unzip, then run the registry script from https://files.acrobat.com/a/preview/07f2ebef-e13c-4a0b-9e69-e79debcf9642

    Good day,

    I had this problem two weeks ago, and you helped me run an executable script file that solved the probem.  But it has now recurred.  I again downloaded the file, extracted it, and ran it.  I got a message that the registry change is already installed and it would not process.  I cannot open pdf files, and I still get the DDE message

    The only other thing I can imagine is to disable Protected Mode [Edit | Preferences | Security (Enhanced)].

    Hi jimmyjack50,

    You might try this out:

    • Go to Task Manager by pressing Ctrl + Alt + Del
    • Click on Processes tab and end all the processes associated with Acrobat

    Now, launch Reader again and let me know.

    Regards,

    Anubha
