If you have acquired the legitimate installer, here are a few tips to ensure a smooth setup on modern Windows (10/11):
C:\G16W). Avoid installing directly to Program Files if possible, as it simplifies setting up environment variables.GAUSS_SCRDIR environment variable pointing to a fast local drive (preferably an SSD) that has plenty of space.
GAUSS_SCRDIR -> Variable value: D:\Scratch (or your chosen folder).Q1: Can I use "gaussian 16w download upd" to get a free version?
No. Gaussian is not free software. Any site offering a "free download with upd" is distributing counterfeit software. Contact your university’s IT for legitimate access.
Q2: How often are updates released?
Typically 2–4 times per year. Major revisions (e.g., B → C) occur every 1–2 years.
Q3: Do I lose my existing jobs when updating?
No. Checkpoint files (.chk) remain compatible across minor updates. Major revisions (e.g., Rev A.03 to Rev B.01) may break compatibility – restart jobs from the last .rwf or reformat .chk files.
Q4: My update fails with "Access Denied."
Run the update installer or file-copy step as Administrator. Gaussian traditionally installs to C:\Program Files\Gaussian, which is protected by UAC.
Q5: How to revert an update?
Restore from your backup. There is no automated rollback. Consider keeping a separate installation for testing updates before applying to production.
After download, check the SHA-256 hash (if provided by Gaussian) or ensure the .zip extracts without error. Example using PowerShell:
