Am running the newest version of Chem3d (I believe and am having issues interacting with Gaussian 16W (in particular, every time I try to do a job, I get an out of memory error and have to modify the job)

With what I have seen so far doing an internet search the problem appears to be that I have to use an earlier version of Gaussian, which I can't get (just recently bought that license for my University). I would much rather use the CHEM3d to set up Gaussian jobs as that is much easier for my undergrads to understand rather than have to teach them how to use Gaussian and Gaussview.

Thanks in advance for any answers

We are not sure about the product for which you have license (ChemOffice Professional or ChemDraw Professional).

Gaussian 16W compatible with Chem3D Ultra as wellas Chem3D Ultra We recommend to retest the problem after reinstalling Gaussing 16W (if you have Chem3D Ultra 19.x).

If yo still run in to any problem, please visit to submit a ticket (or send an email to, to get assistance from our Tech Support Team.
