Touchstone Re.exe.config

<add key="LogEditor" value="C:\Program Files\Notepad++\Notepad++.exe" />

If you wish to override the default entry for Notepad, add the following with a new value (example here is for 500 MB) to one or both configuration files (noted above):

<add key="MaxNotepadLimit" value="500" />
