    UNINSTALLING READER 10 PROBLEMS

    RONALD RYAN LAW OFFICE

      How to uninstall Reader 10 or make Acrobat 9 the default reader of .pdf files when all efforts to do both according to web postings have failed?

       

      I have the full paid version of Acrobat 9, but I installed 10 Reader which I now know was a mistake. Every time a .pdf file is to open it opens in Reader 10 and I do not want that. I tried to uninstall Reader 10, but it failed on every attempt with error 1402. Could not open key: UNKNOWN\fdf\AcroExch.FDFDoc\ShellNew. Verify that you have sufficient access to that key, or contact your support personnel.

      I also tried to make Acrobat 9 the default opener for .pdf files, but it was not listed in the list of programs even when I tried to browse for it.

          The problem is you cannot have Reader 9 and Acrobat 9 or Reader X and Acrobat 10 on the same Windows computer. The only Reader/Acrobat programs supported is Reader X and Acrobat X which was specifically designed to work together. It was never a priority to get them to work properly together, but for security reasons (Reader X Protected mode), Adobe finally put the effort to get them to play nice.

            Are you really sure that Acrobat 9 is still installed, if you can't even browse to the program?

             

            I've successfully installed Acrobat 9 Pro Extended and then Adobe Reader 10.1.0 and both programs appear to work properly.

             

            In my Adobe Reader X setup script I add the following registry keys after the Reader installation - please note that your directory names may differ depending on the operating system (language):

             

            Windows Registry Editor Version 5.00


            [HKEY_CLASSES_ROOT\AcroExch.Document\shell\open]

            @="Open with Acrobat 9"


            [HKEY_CLASSES_ROOT\AcroExch.Document\shell\open\command]

            @="\"C:\\Program Files\\Adobe\\Acrobat 9.0\\Acrobat\\Acrobat.exe\" \"%1\""

             

            [HKEY_CLASSES_ROOT\AcroExch.Document.7\shell\Open]

            @="Open with Acrobat 9"

             

            [HKEY_CLASSES_ROOT\AcroExch.Document.7\shell\Open\command]
            @="\"C:\\Program Files\\Adobe\\Acrobat 9.0\\Acrobat\\Acrobat.exe\" \"%1\""

             

            [Edit]

            Having applied these changes you can right-click on a PDF to invoke the context menu and decide whether to open it in Reader or Acrobat
