Assuming you have a valid license (a license file named gaussian-16.lic and a download link from Gaussian, Inc.), here is the correct procedure.

Error 5: Slow performance compared to Linux

Cause: Windows NTFS file system handles temporary scratch files poorly.
Fix: Set GAUSS_SCRDIR to a RAM disk (using tools like ImDisk) for ultrafast I/O.
