    Fatal error with 9.3.3


      I had version 9.3.1 and when I clicked on a file I'd get a "Fatal error: Acrobat failed to connect to a DDE server" So I uninstalled and downloaded 9.3.3 and now when I click on a PDF file, I get nothing. I've gone into control panel and done the repair thing - it seemed to be re-installing the program. When I go to programs and try to open the program, nothing happens. Any ideas? or where I can get an old version that WORKS!??

            I have never seen this message, nor do I know what it means.


            Just F.Y.I. you can get any previous Adobe Reader version by navigating the Adobe FTP site ftp://ftp.adobe.com/pub/adobe/reader/win/

              This seems to be a problem where the access of Adobe Reader is being blocked by either some Antivirus setting or any other application. Please try:


              1. Get the latest version of Adobe Reader 9.3.4 from http://get.adobe.com/reader/?promoid=BUIGO install and check if the issue gets resolved.


              2. If not check Antivirus/ antispyware if their settings are blocking Adobe Reader. Change the settings or turn them off.


              3. Repair the installation from “Add and Remove” (control panel) entry, kill running AcroRd32.exe processes and then restart the system.

                Thanks for your suggestions thus far. I did a search on Adobe for DDE server and I can't understand what I read but it may be a Windows server or something in Windows that allows Adobe to work properly??? I still need answers if anyone has any.

                  From Windows "

                  Enables a DDE server application to impersonate a DDE client application's security context. This protects secure server data from unauthorized DDE clients.


                  I haven't tried this yet but looks like a place to start:


                  You may try the steps as below and check if the issue gets fixed.


                  Note DDE is Dynamic data exchange and the Explorer uses DDE to open Office documents (supposed you open the document from the explorer window).

                  DDE Share is a tool for managing the way programs communicate and share data over a network. If you wish to disable this prompt then you may follow the below steps. Here, this issue could occur if you have installed any security program on your computer you may get this error message.  Try to turn off the on-access scanning for the application control policy in your security program and check for the issue. To do that you need to contact your security program support team.
