Chem3D: MOPAC, GAMESS, and Gaussian interfaces are not available in my Chem3D Calculations menu

MOPAC, GAMESS, and Gaussian interfaces are not available in the Chem3D Pro level. In order to access this, you need Chem3D Ultra.

They are also not available with the trial version of ChemDraw.

 

ChemDraw Professional activation codes will activate Chem3D as Chem3D Pro level only.

You will get the various interfaces once you activate the product using ChemOffice Professional/ChemOffice + Cloud activation code.

 

I didn't find the MMFF94 function in my Chem3D application
