Can not open Adobe XI nor will it respond (shows "not responding" in the task bar window). It does not let me exit the window, I have to restart the computer. Can anyone Help. I reinstalled the program w/no resolve. Then a error box appeared, "Fatal Error. Acrobat failed to connect to a DDE server". I have Windows 7.
Some users were successful in resolving 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 11.
Please export the registry before making any changes to it.
