acrobat failed to connect to a dde server

[Jeffrey Bodine]

We are printing company using Acrobat 9.5 and Kodak SmartBoard to print to Kodak Digimasters. The PC is running Windows 7. When we launch SmartBoard (which will launch Acrobat) we get the error acrobat failed to connect to a dde server. When we try to just open Acrobat the cursor spins and then nothing happens. We are desperate to get this open as we need to print. Please help. I have tried changing the registre of the application from acroview to acroviewa9, etc.

That an incorrect change. The topic name did not change in Acrobat 9 and remains acroview. One thing to check is that you are not trying to start Reader from an app that is running as administrator.

It turns out that there was a Microsoft security update that turned the windows firewall on and it was blocking acrobat from opening. We are an all Mac shop so it took us a while to find that.
