I am unable to find MestRenova in ChemDraw installer 16.0. Why?
MestRenova is a third part application and it is not a part of ChemDraw/ChemOffice installer since version 15.0 (in version 15.0 and 16.0). Earlier it used to be till version 14.0. Hence when installing the our ChemBioDraw/ChemOffice/ ChemBioOffice software you used to get this application installed. I can still find that MestRenova are offering special installer for ChemDraw users. You can get information from their website.http://mestrelab.com/mnova-lite-525-for-chem-draw-users.html
For more information on this, you can contact them.
Also, you can try predicting NMR using ChemDraw software. For that, please go to Structure - Predict 1H-NMR shifts and 13C-NMR Shifts.
