Where is the registry key for the Access client setting "Ignore DDE requests"

Question

I have an Access program that uses dde requests to open orders in another Access database. This process suddenly stopped working for one client. I am trying to debug what is going wrong. It would be nice to know where that little switch is in the registry for when I look at his computer.

Answer 1

According to Process Monitor, the registry value on my machine (Access 2010) appears to be

HKCU\Software\Microsoft\Office\14.0\Access\Settings\Ignore DDE Requests

It originally didn't exist, but when I selected the option in Access the registry value was created as REG_DWORD with a value of 1.
