The default Windows installation by 'Setup.exe' will create a folder typically 'C:\Program Files (x86)\YAMAHA\MEGAEnhancer ver.1.5'
This folder contains not only the actual program, but also an additional folder named 'Manual', which contains PDF versions of the 'MEGAEnhancer ver.1.5 Owner's Manual' in English, German, French, Spanish and Japanese.
