  • 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.

  • I have Acrobat XI on a PC and have received a Fatal Error message indicating that "Acrobat failed to connect to a DDE Server."  Acrobat will not open now.  How do I regain access to the program?

    I have Acrobat XI on PC.  After trying to convert a webpage to PDF, I received a Fatal Error message indicating that "Acrobat failed to connect to a DDE Server."  Now, the program will not open.  How do I regain access to the program?

    I have Acrobat XI Pro and have been experiencing all sorts of "freeze ups" with it ever since Adobe released the new Acrobat DC the other week.  I see that an automatic update was pushed down to my Acrobat XI Pro at the same time.  Is this the first issue you have encountered with your Acrobat XI, or have you been having other issues suddenly as well??  Just wondering ...

  • 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.

    Hi Bruce,
    Please open registry by typing "regedit" in the Run window (Windows + R)
    Now, navigate to "HKEY_CLASSES_ROOT\acrobat\shell\open\ddeexec\application and changing the Key from "AcroviewA10"  to  "AcroviewR10.
    Now, try launching Acrobat and let me know if the issue resolves.

  • I get a error message "Acrobat failed to connect to a DDE Server.

    I bought a copy of Adobe Acrobat XI and installed it on my computer.  It worked good for about a month.  Than it would not load the program so I could.  I tried to open as the adminstrator and the program still does not open.  I ran a troubleshooter and it said"Acrobat failed to connect to a DDE Server".  What can I do to fix this problem so Acrobat XI will run?

  • Adobe Reader won't open PDFs

    Why do I keep getting an error message when I try to print a PDF with Adobe Reader? It says that I have to sign the user agreement. I have already done this at least 10 times....

    The ikon appears on my desktop ok.  But when I click on it I get the following message:
    Adobe Reader could not open "Paul Voigt and Edison Bell.pdf" because it is either not a supported
    file type or because the file has been damaged (for example, it was sent as an email attachment and
    wasn't correctly decoded.
    I get this message every time I try to use Adobe Reader!

  • Adobe reader won't open PDF file

    I have Adobe Reader 9 and Windows 8 on a Dell computer. When I try to open a PDF file from a website it sends me to my Library on my computer and won't open the file. If I try to open a PDF file from my Desktop, it opens OK. What can I do to fix this?

    Do you use Firefox' own PDF viewer, or the Adobe Reader plugin?  See http://helpx.adobe.com/acrobat/kb/pdf-browser-plugin-configuration.html

  • Adobe reader won't open pdf files

    I was hoping someone can help. I have Windows XP, and I use Firefox as my web browser. I have installed Adobe Reader, and when I click on a pdf link, in the lower left field of the screen it reads as follows: 'connecting, waiting, stopped' it repeats this over, and over, and over. I eventually have to right click and save the link to the desktop, but this is becoming entirely too frustrating........I have since uninstalled Adobe, and re-installed it, but nothing changed. I even uninstalled Firefox and re-installed, but to no avail.
    If anyone has a fix, I am open to your suggestions.
    Thank you.

    Have a look here:
    http://support.mozilla.com/en-US/kb/Opening+PDF+files+within+Firefox
    (http://preview.tinyurl.com/5a6klx)
    it's probably an issue with the Firefox plugin for Adobe Reader.

  • 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 won't open due to dll error

    Upon opening any PDF or acrobate reader 9.3 on its own, I get the error below:
    AcroRd32.exe -entry point not found
    The procedue entry point
    ?str@?$basic_ostringstream@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@QBE?AV?$basic_str ing@DU?$char_traits@D@std@@V?$allocator@D@2@@2@XZ could not be located in the dynamic link library MSVCP80.dll.
    Where can I get a new copy of this DLL to work with acrobat reader? I beleieve it's supposed to go in system32 or system so some instruction on where to download the correct files, where to copy them to and any other procedure necessary would be appreciated.
    By the way, uninstalling and re-installing the application did not help.

    What is your Windows version?
    What is the version of your MSVCP80.dll?
    You can find the latest version of the VC80 CRT (for 32-bit Windows) here http://www.microsoft.com/downloads/details.aspx?FamilyId=32BC1BEE-A3F9-4C13-9C99-220B62A19 1EE
    Sorry, here is a newer one http://www.microsoft.com/downloads/details.aspx?familyid=200B2FD9-AE1A-4A14-984D-389C36F85 647
    Run Microsoft Update after installing the latest VC80 CRT to apply any available security updates.

  • Q: What does this error message mean and what's next: Acrobat [(XI (11.0.06)]: "Acrobat failed to connect to a DDE server"?

    Acrobat Reader

    Sorry, I didn't read your question carefully, so my earlier reply is incorrect.
    You need to make a change to the Windows registry:
    HKEY_CLASSES_ROOT\acrobat\shell\open\ddeexec\application: change "AcroviewA10"  to  "AcroviewR10"
    To do this automatically, download ddeexec.zip, unzip it, then double-click on the extracted file to run the registry script.
