Hi, I have problem in combining multiple files into single pdf. It seems to be hanged forever and finally pops an error window "Fatal Error - Acrobat failed to connect to a DDE server". Does anyone know how to solve it??
Acrobat version: 9.5.2
Here is the situation:
The user will be fine opening and printing to PDF.
Suddenly: When opening a PDF or attempting to print to PDF the message:
"Fatal Error - Acrobat failed to connect to a DDE server" I have users experiencing the exact same message only in Citrix (never on a local machine). The issue is intermittant. We are using Adobe Acrobat Professional 9.5.1. We do not have Symantec Endpoint security enabled. Back leveling to 9.0 is not an option.
Any suggestions would be appreciated!!
We were successful to resolve the issue for Acrobat X by navigating to HKEY_CLASSES_ROOT\acrobat\shell\open\ddeexec\application and changing the Key "AcroviewA10" to "AcroviewR10.
try to change the similar key for Acrobat 9.
Please export the registry before making any changes to it.

I just encountered this problem myself. It occuered as soon as I uninstalled Adobe Air. I reinstalled Adobe Air and the problem was solved.
I am running windows 7 and I am using Acrobat X Pro; hopefuly this solution will work for you as well.
The suggested solution of modifying the registry key worked for my installation as well - Win7x64, Acrobat Pro XI 32bit
When initially installed the upgrade from X there were no issues. Then installed PaperPort 14 and began having trouble where the Nuance product insisted on being the primary app for PDF's in MS Office products and IE9.
Resolved that by repairing the Acrobat XI installation.
Then found that could no longer double click on a PDF and open it, or drag the file to the Acrobat window and open it. Could only open a PDF file from within Acrobat XI.
Editing the registry key as described resolved the problem of not being able to directly open a PDF.
Changing the registry key was not an option for me as it was already ending with R10, not A10.
Any other suggestion?
Could this have to do with installing PDFill (PDF manipulation software)? I installed it recently but it didn't cause problems until now.
