On ENLIGHTEN versions 2.5.3 and after, the logfile (enlighten.log) is stored in the EnlightenSpectra folder.
For older versions of ENLIGHTEN, the Windows logfile is saved in C:\ProgramData\wasatch_applog.txt. The “ProgramData” folder is normally hidden by Windows, so the only way to access it is to manually type “C:\ProgramData” into the navigation bar of a Windows Explorer window.
This file may be viewed in Notepad/Wordpad, or emailed along with support tickets (recommend zipping first 🙂 ).
