Can't print pdf docs. Keep getting failed to connect to dde server. How do I fix?

I have Adobe Reader X and I can not open files, or print them. I keep receiving a fatal error-DDE server not found. I have tried reloading Adobe, rebooted, and nothing seems to work. I have no trouble accessing my browser, can print nonadoble files. Everything else is running fine. What can I do?

Hello,
In order to change the default reader for PDF files (to not open PDF files with Firefox's internal PDF reader), follow these steps:
#Go to ''Tools'' > ''Options'' (or ''Firefox'' > ''Options'').
#In the Options window, select the ''Applications'' tab.
#In the ''Search'' field, type ''PDF''. You should find ''Portable Document Format (PDF)''.
#On the right handside you should find an ''Action'' column. Use that to select your favorite PDF reader. In order to view PDF files in Firefox, choose ''Preview in Firefox''.
Did this fix your problems? Please report back to us!
Thank you.

I previously was able to wirelessly ePrint to my HP Photosmart Plus e-All-In-One B210a using both my iPad & iPhone (both run IOS 5.1). For some unknown reason neither one can now print. I keep getting a message that the printer is no longer available. My MacBook continues to print ok. Any ideas?

Reboot everything. Router, printer and pad. If it used to work, it will again. It just lost itself somewhere.

HT4519 I have a yahoo email account and i keep getting an "error connection to the server failed"

The email account i have always used on my ipad mini is through yahoo. Now i keep getting an error "connection to the server failed" when trying to access my email.

its a common message but could be due to several possible causes
try this
close the mail app by double tapping the home button, swipe the screen until you see the large icon of the mail app. Swipe the app up and off the screen to close. Tap the home button to return to home screen. Open mail app again.
if that didn't work, then...
Reboot device by pressing both the home button and sleep/wake (power) buttons at the same time for 10-15 seconds until the apple logo appears on the screen, then let go.
If that doesn't work then reset the device by going to settings/general/reset/reset all settings (or for network connection issues 'reset network settings').
(no media or data will be deleted from the device, this will only take a minute).
Unplug your wifi router for 5-10 minutes and at the same time reset settings on the ipad
settings/general/reset/reset all settings
(no data will be lost)

I can not open any pdf file... . Fatal error. Acrobat has failed to connect a DDE server

fatal error
Acrobat has failed to connect a DDE server....
What can I do?

Did you register and activate Acrobat? I don't remember the DDE issue off hand, but it should not be occurring with the regular Acrobat installation.

"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?

Failed to connect to DDE Server Acrobat XI Pro Windows 8.1

I had installed Acrobat XI Pro on a Windows 8.0 notebook computer and it was working fine. When I upgraded to Windows 8.1 a few months ago, I started getting intermittent problems/error messages when I would try to open a pdf file by doubleclicking on the file either in a folder or on the desktop. The file wouldn't open and the error message was "Failed to connect to DDE Server." I can still open the files by doing a File, Open from inside the software, so it's not an insurmountable problem, just annoying. Any suggestions on how to fix this?

Hi TreeLady ,
Thanks for posting on forums, DDE server was a part of Windows XP, it was removed from Windows Vista and above. However, if you are getting this error in Acrobat, try the following.
(This error occurs when you have more than 1 process of Acrobat running)
1) Go to the task manager by presiing Ctrl+Alt+Del
2) Go to the processes in Task Manager
3) End all processes related to Acrobat
4) Launch Acrobat again.
Also, to find the root couse or to isolate the issue you can try the following.
1) Click on start
2) Type RUN
3) Type MSCONFIG
4) Go to services
5) Hide all Microsoft services
6) Disable all Services (Except Microsoft)
7) Restart your machine
8) Launch Acrobat to check if you get the issue.
This would help us to understand if Acrobat or any other third party process is not allowing Acrobat process to end causing a conflict .
Thanks,
Vikrantt Singh

Acrobat Pro XI Fatal Error Failed to connect to DDE server

Can't open file ... error msg "cannot connect to DDE server"?

I can't open my pdf files from Outlook or just open Acrobat. If it does open, it says Acrobat failed to connect to DDE server? I'm using Acrobat Pro 9.3, I think as it updated. I have Win7 with current updates on a new Sony Vaio laptop.
I looked at the other msgs but I am using Norton Anti-Virus not the one mentioned. I am upgraded to Win7 and IE8. All worked ok before switching to new computer and in starting to use Win7 & IE8.
Thanks!

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.

Fatal Error: Failed to connect to DDE server

I've read the other posts about this problem, but none seem to fit my situation.
This happened while trying to use a 3rd party program Typhoon AutoRun to test autorun files for CDs of our Ebooks that we're burning. Each of these Ebook CD projects has 6 PDF files to open; 1 Mobipocket, 1 HTML. Of course, the only problem occurs with the PDF files.
Let me start by saying that I was using Acrobat 6 until September, when we upgraded to CS 4, and never experienced this issue.
And after installing Acrobat Pro 9, I hadn't any difficulty until TODAY.
Order of events: I opened a past completed project in Typhoon Autorun to test the file before burning to CD.
When I clicked on one of the PDF document buttons, the first thing that happened was Adobe Active X 9 attempted to run. BUT the Active X failed to install on the first attempt:
"Error 1904.Module
C:|WINDOWS\system32\Macromed\Flash\Flash9f.ocx failed to register. HRESULT -2147220473. Contact your support personnel."
The Typhoon Autorun program continued operating and opened the project's PDF documents without any difficulty -- all 6 opened, one after the other, when I clicked on their buttons.
I closed out the error message, closed out the Typhoon Autorun project I was testing to work on another Typhoon Autorun project. When I had that one finished, I tested it as I had the one previous.
This time when I clicked on a button to open one of the PDF button, the Adobe Active X 9 program loaded and INSTALLED successfully.
THEN, the PDF document opened. But when I attempted to open any of the other 5, they did nothing. I double-checked my Typhoon Autorun project files, but all of the settings were correct. I tried testing my project again. This time NONE of the PDF files would open.
I closed the Typhoon Autorun program and attempted to open Acrobat Pro 9 immediately after. I tried clicking on the shortcut button several times with no result. After several minutes, literally, I received the "Fatal Error: Failed to connect to DDE server" --- actually, several instances of that message to correspond with all the times I'd attempted to open the program.
I shut down my computer, rebooted, reopend Typhoon Autorun and tried to test a different project.
Again, Adobe Active X 9 installed. (If it's already installed why is it reinsalling???)
And again, only 1 PDF file would open. Then none of the others. I shut down Typhoon Autorun and tried to open Adobe Acrobat again, and it wouldn't open.
The problem seems to be appearing when Adobe Active X 9 installs, and it's doing that automatically, without asking.
I never had this problem when I used Adobe Acrobat 6 (I'm really beginning to regret upgrading)
I never had this problem before this Active X 9 started installing.

"acrobat failed to connect to dde server" when openning Adobe Acrobat XI PRo

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.

I can no longer print .pdf docs, I get: lxbzgf.DLL was not found & can not load library LXBZPRP.DLL

When trying to print a .pdf doc, it now fails and I get the following dialog box: "lxbzgf.DLL" was not found" and then after closing the session, pops the following dialog box which says: "can not load library "LXBZPRP.DLL"
I think it is related to laptop operating syst. (Windows XP Nedia Center Edition) and latest Adobe Readed XI. Can you help with the proper diagnostic and what should I do, please?
Thanks,
Daer Rotciv

I really don't know what SP3 is but my Gateway laptop operating system is Windows XP Media Center Versión 2005 with Update Rollup 2.
The only additional information I see on this system is MS WIN MCE GTW US V1.5 07/06. 7515344

I can't print PDF docs since Reader XI update

Help!!!!!!! I can't print PDF documents since updating to Reader XI. Had no problems before this update. I have read other users posting and tried one "fix" that was suggested suggesting user try to print docs as "image," but that choice was not active to select. I can't print even older PDFs that are on file in my computer. Please advise - this is interfering with my business. Thanks. I get an error message indicating "no pages selected to print" even though it defaulted to Print All. I selected by one page, pages 1-5, etc. with no success. Windows 7 system.

Pat, that did not fix the problem. I still get the messages that the document cannot be printed and that no pages are selected; the print dialogue box shows that “all” pages are selected. I get the message even if I manually select “pages 1-7” etc. I tried deleting Adobe and reinstalling it but I get a 1311 message that seteup.exe cannot be located. I tried downloading just the Adobe Reader printer drivers from your site and get a message saying that the download was not successful. Please help.
