Question:

After installing the ChemOffice 18.x Trial, I cannot find the option for the Mopac, Gamess or Gaussian interfaces.

Answer:

This problem only occurs when using a version of ChemOffice or Chem3D that has not been activated, such as the trial. This behavior can also occur if you are using a ChemDraw Professional license, which does not include these interfaces.

Testing these interfaces is not possible if you are using the free trial.

Once you activate the software with a valid activation code for ChemOffice Professional these options will become available. Then you can download and install the additional components to load each interface as needed. Please consult your Chem3D User's Guide if you need assistance completing this final step.
