Fatal error Acrobat failed to connect to DDE Server

I just purchased the Adobe Acrobat xI Pro & installed. I get a Fatal Error message when I try to open the program. I am running Windows7. What is the problem?

Hi HP2,
Try launching the application as Administrator and check.
Also update Acrobat to the latest patch i.e. v11.0.08 and check.
You might also want to repair Acrobat from the Control Panel> programs and check.

Adobe Reader 9.1 - Fatal Error : Acrobat failed to connect a DDE server

Hi Everyone,
I have some users telling me that when they try to open a pdf attachment in Outlook 2007. Nothing happens. The system just sits there as if you did not click on the attachment. If you wait long enought a popup box from adobe reader comes up and says:
Fatal Error
Acrobat failed to connect a DDE server.
All the PDFs are very simple, just simple scanned images or converted over from a document into a PDF.
I've tried repairing the install and still had no luck - same behaviour. The only way the pdf opens is if we go into task manager and close the AcroRd32.exe process or logoff and log back in.
If it helps, the most recent system change was the upgrade to IE7 and a new anti-virus software.
Thanks,
KEvin

No solution I am afraid but same problem, running full version of AVG and problem hit immediately after Adobe Reader 9.1 upgrade. Pretty darn sure problem is in the upgrade but the relevant Restore Point was overwritten before I figured it out. Any advice welcome.

What do i do when I receive Fatal Error Acrobat failed to connect to a DDE Server

Can I get some help? I can't get the Acrobat XI Pro to open...I get the Fatal Error Acrobat failed to connect to a DDE server.

You already setup a discussion for this, no need to create more. It has only been an hour since your last post. Considering this is Sunday, you may have to wait a while, though it really comes down to when someone with an answer happens to stop by. We are just users, not employees of Adobe (that is why it is called a user-to-user forum). I remember seeing posts on this in the past and suggest you do a forum search for past posts. I do not have the solution at hand.
There are several posts under "DDE Server Acrobat Installation" search.

Acrobat X Pro does not open, gives fatal error - "Acrobat failed to send a DDE command"

Acrobat X Pro does not open and gives fatal error - "Acrobat failed to send a DDE command"
It either does the above or the application starts and is listed in the system processes but never physically opens on the desktop for viewing.

AA 9 will not work for anything but the print function from WORD 2010. The only version of Acrobat that is compatible with OFFICE 2010 for PDF Maker is AA X. Thus, open WORD and print to the Adobe PDF printer. Then open the pdf in Acrobat. Go to FORMS>Add or Edit fields. Since you have no fields at present, Acrobat will ask if you would like to detect form fields. Answer yes and you will get a first cut at the form fields. Yes, you will likely have to add some more and change the ones that Acrobat estimates, but you are on your way.
The other two options you have is to go back to WORD 2007 or earlier or upgrade to AA X (or find someone with AA X and WORD 2010). These methods are pretty much your options with the software combination that you have.

[Moved from the Premiere Pro forum... Mod]

Hey,
You might try deleting all processes related to Acrobat from the Task Manager and then launch Acrobat again.
Also, please repairing Acrobat from the Help menu.
If still you get the same error, then press (Windows+Run) and type "REGEDIT"
Go to "HKEY_CLASSES_ROOT\acrobat\shell\open\ddeexec\application" and tell me if the given key is AcroViewA10 or AcroViewR10.

"Acrobat Failed to Connect to DDE server"

Hi
I get a fatal error when I try to open a PDF document by double clicking on it. I am using version 10.1.4.
It just started recently. It was working before. I don't know why it is not working now.

Hi,
No, the Privileged key is not present at all in HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\10.0\.
I See a field AdobeViewer in which I see "TrustedMode" set to 0.
Also I noticed that the value for HKEY_CLASSES_ROOT\acrobat\shell\open\ddeexec\application is "AcroviewR10" even after the restart.
But What I found was that the shockwave flash plugin is causing some problem with Acrobat reader. WHen ever I enable this plug in I am not able to view the PDF documents and I get the original error "Failed to connect with DDE server". If I disable the plugin and restart then I am able to view the docs. But I can't browse web sites which need flash plugin. So I dn't know what exactly is the issue here..
Any more suggestions?

What does acrobat failed to connect to DDE server mean?

What does it mean ? Acrobat failed to connect to DDE server

Hi,
DDE stands for Dynamic Data Exchange, and it is a way for two programs to communicate with each other. http://msdn.microsoft.com/en-us/library/windows/desktop/ms648711(v=vs.85).aspx
Adobe Reader, or (Acrobat Standard/Pro) would be an example of a DDE server, in that when they are open they can accept unsolicited communication from client programs.
One client could be the fast launch utility.
Because the DDE server is local to your machine, only a server name needs to be decided upon. For instance prior to version 10 Adobe always used 'Acroview' as it's DDE Server Name. For some reason, Adobe claims 'security', They decided to change the DDE Server name for version 10 to AcroviewR10 for reader, and AcroviewA10 for Acrobat.
Because there was decades of old code which had never needed to change many programs stopped working, and began claiming that they couldn't connect to Acrobat.
Adobe, rightly, claimed that it was a bad practice to hard code the DDE Server name into your code, and that a better practice is to get the value from the Registry.
That would have been helpful but Adobe seems incapable of remembering to update this registry key when upgrading their software, even though they update the setting in their software.
For instance right now Adobe is setting the DDE Server name in the registry to AcroviewR10 for Reader 11. What is worse is that their software only responds to AcroviewR11.
So if you hardcode the server name, or create a function to determine what it should be, than you might be ok, but if you accept their good coding practices your applications will fail to work as expected, and your clients will think it is your fault.
Hope this helps.

Fatal Error Acrobat failed to send a DDE command

Hello all. I have a fillable form I developed using word 2010. I am trying to convert it to a PDF form. I open acrobat and select star from wizard from the Forms menu. I browse to find the word document and open it. I save the PDF document and everything looks good. I get a progress bar that says "Please wait, reading Adobe PDF". This is very slow progress and then I get the Fatal Error message "Acrobat Failed to send a DDE command". I click ok and the progress bar continues still very slowly. I get the same message again. I click ok and the progress bar continues. The progress bar gets to the end and just stays there. Nothing happens. I waited for an hour and then cancelled it. When clicked cancel, the PDF document opens with my form but without any fillable fields or drop down menus. I tried to do it again a few times and I get the same error message. I am using Adobe Acrobat 9 pro version 9.4.2. Thank you in advance for your help.

Does this happen with all PDF files? Is a modal dialog already open in Acrobat when you are trying to open a PDF?
