Place any number of ES/MC/LE executables to any of the "C:\Program Files\TrustedClean\MCLE" subfolders. You MUST place the executables to Local, Network or NTAuth subfolders, otherwise they won't launch! Works with all .exe files. Filenames don't matter.
If you are unsure, use NTAuth subfolder. NTAuth = sexe.
Local folder might give more euphonic and extended sound, at the expense of slightly higher distortion. Network folder is best for running secondary instances.
