Getting Started with Gaussian 16 for Windows Gaussian 16 is a leading software suite designed for electronic structure modeling, utilized by chemists and physicists to predict the properties and reactions of molecules. As the latest iteration in the Gaussian series, it introduces advanced features such as enhanced geometry optimization for "floppy" molecules and support for broader basis sets. System Requirements

Drawback: No GPU acceleration, slower file I/O, and no native integration with GaussView for Windows.
If you’ve landed on this page, you are likely a computational chemist, a materials science researcher, or a graduate student looking to run high-level ab initio calculations on a Windows machine. You typed in the phrase “download gaussian 16 windows new” because you need the latest version of one of the most powerful quantum chemistry software packages available.
Cause: The new Windows version fails to allocate large memory above 4GB by default.
Fix: Add %Mem=32GB (or your value) in the route section of your input file. Also, ensure Windows page file is set to "System managed."
Once you have downloaded the official G16_RevC.XX_Win64.zip, follow this guide:
Once you have the installation files, follow these steps to set up the software: G16W System Requirements - Gaussian.com
