To get their text editor working you must navigate to the bin folder within the DayZ Tools Folder and then head down to the workbench.
If you launch the workbench and you get the following issue (Press Retry to debug the application- JIT must be enabled) with an output that complains at you about an issue, all you have to do is Enable JIT by changing the file within your configs
Search for file 'machine.config' , I found it here:
C:\Windows\Microsoft.NET\Framework\v2.0.50727\CONFIG
Find the line <!-- <system.windows.forms jitDebugging="false" /> -->
and change it to true.
Then just restart your PC and then Boom. working Enfusion Text Editor (Haven't worked out whats so good about it yet but there you have it)
