When trying to use the Gaussian client in Chem3D, I get the message:
Sorry, the Gaussian calculation failed; please see the .out file for details.
When using the Gaussian client for the first time, you are prompted to find and select the Gaussian application. The problem is that you have not browsed for and selected the Gaussian 94W program, which is required to use any of the options in the Gaussian menu in Chem3D. What you have selected is our Gaussian Client. Our Gaussian client is only an interface between Chem3D and Gaussian 94W. Gaussian 94W is a separate application that you need to purchase from Gaussian, which is a separate company.
