A: Yes, Windows 11 is fully supported for the 64-bit version. However, be aware of the potential performance issues with CPU core scheduling mentioned earlier.

| Issue | Symptoms | Likely Cause | Solution | | :--- | :--- | :--- | :--- | | | Setup.exe doesn't run, or errors during file copy. | Insufficient permissions; security software blocking installation. | Run as Administrator; temporarily disable antivirus and firewall; ensure you are not using a network drive as the installation target. | | Serial Number Rejected | "Invalid serial number" error during installation. | Typo; using a license meant for a different version (e.g., Linux on Windows). | Double-check the serial number from the official documentation; ensure it is for Gaussian 16W (Windows) . Do not use generic keys found online. | | Scratch Disk Full | Job fails with "Error: Unable to write to scratch directory" or disk full messages. | Insufficient space on the drive where GAUSS_SCRDIR is located. | Free up space; move GAUSS_SCRDIR to a larger, faster drive; set up a dedicated high-capacity scratch disk. | | Poor Parallel Performance | Increasing %nprocs does not speed up jobs; sometimes slows them down. | Windows CPU scheduler inefficiency with the 32-bit version; core contention. | Ensure you are using the 64-bit version ; check that hyper-threading is not causing logical core overload; set %nprocs to the number of physical cores only. | | Memory Exhaustion | Job crashes with "Out of memory" error. | %mem set too high, causing swapping; or memory limit too low for the method/basis set. | Decrease %mem to leave ~2GB for the OS; upgrade physical RAM; use a less memory-intensive method (e.g., DFT instead of CCSD(T)) for large molecules. | | Slow Calculation | Jobs are unexpectedly slow, even on powerful hardware. | Scratch directory on a slow HDD; memory limit incorrectly set; single-core bottleneck. | Move scratch directory to an NVMe SSD; increase %mem ; ensure %nprocs is correctly set; use the 64-bit version. | | Path/Character Errors | Job fails to read input file or write output. | Non-ASCII characters in input file paths, filenames, or within the input file. | Use only English letters, numbers, underscores, and hyphens in all paths and filenames. Avoid spaces. | download+gaussian+16+windows+new

The cost of Gaussian 16 is a significant factor. The license is a , after which you can continue to use the version you licensed. Here is a simplified breakdown of the pricing (USD as per the official US academic price list):

Gaussian generates massive temporary files during calculations (such as two-electron integrals). Gaussian 16 is the latest edition of the

Historically, Gaussian was optimized for Unix-like systems (Linux, macOS). However, with the rise of powerful Windows workstations (featuring NVIDIA GPUs and high-core-count Intel/AMD processors), Gaussian, Inc. now offers a fully supported native Windows version. The Windows builds (Revision C.02 or later) include:
