Error Running Dexterity in Debug Mode

Microsoft Dynamics GPI was working on upgrading some Dexterity code a little while ago and encountered a problem in the code. I tried to enter debug mode and received a message that Utilities for the custom dictionary needed to be run:

You need to run MIS_AMS_Ext_160.dic Utilities before you can run MIS_AMS_Ext_160.dic. Do you want to launch MIS_AMS_Ext_160.dic Utilities now?

I spent a little while looking into why this was happening and found a few posts saying to copy the Dex.ini file into a Data folder in the dictionary location, but this had no effect.

Instead the Dex.ini file should be copied into a folder under the install location of Dexterity, which for Dexterity 16 (Microsoft Dynamics GP 2016) is, by default:

%ProgramFiles(x86)%\Microsoft Dexterity\Dex 16.0

Once the Dex.ini file had been copied into the installation folder of Dexterity, I was able to enter debug mode without further issue.
