I can't install the 8.1 update Acrobat Pro patch (either standalone or with Adobe Updater.) An error message indicating the patch fails because the application was modified since original installation. BUT IT WASN'T. I have uninstalled & reinstalled Acrobat, but still can't install the patch. Can you suggest a fix?
