As of 2025, Gaussian Inc. has not released a Gaussian 18 or 20. Gaussian 16 (released 2016) remains the latest version, with periodic revisions (Rev A.03, B.01, C.01). With the rise of machine learning potentials and GPU-accelerated codes, Gaussian 16W is showing its age in raw performance. However, for reliability, documentation, and validation, it remains unmatched in many pharmaceutical and academic labs.
What about Windows on ARM? Currently, Gaussian 16W is x64-only. It may run under emulation on Snapdragon X Elite chips, but without support.
Pro tip for the future: Run Gaussian 16W inside a Windows VM on a Linux host? Not recommended—severe performance penalty. Instead, dual-boot or use WSL2 with the Linux version. gaussian 16w
Use GaussView’s builder to sketch a molecule. For example, a caffeine molecule:

DFT is the most widely used method in Gaussian 16W due to its favorable balance of computational cost and accuracy. Instead of solving for the many-body wavefunction, DFT solves for electron density.
For decades, computational chemistry has been a cornerstone of modern scientific discovery, allowing researchers to predict molecular structures, reaction pathways, spectroscopic properties, and thermodynamic data without setting foot in a wet lab. At the heart of this revolution sits Gaussian, a software suite synonymous with electronic structure modeling. While Gaussian has historically been associated with Linux clusters and Unix workstations, the release of Gaussian 16W has brought the full power of this industry-standard software to the Microsoft Windows environment.

Whether you are a graduate student modeling a new catalyst, a pharmaceutical researcher optimizing drug-receptor interactions, or a material scientist exploring polymer properties, understanding Gaussian 16W is essential. This article provides an exhaustive deep dive into Gaussian 16W—its features, installation, workflow optimization, and how it compares to its Linux counterpart.
GaussView 6 is a memory hog. Launch your Gaussian 16W jobs from the command line, then close GaussView. Let the calculation run overnight without screen savers or heavy browsers.
Gaussian 16W refines the SMD (Solvation Model based on Density) continuum solvation model. This allows researchers to simulate the effects of solvents (water, benzene, DMSO, etc.) on chemical reactions, crucial for drug design and catalysis studies.
Many chemists are not system administrators. With Gaussian 16W, you don't need to learn bash scripting, ssh, rsync, or queueing systems (PBS/Slurm). The software installs like any other Windows application, and jobs can be started by double-clicking an input file.
