(1)The SmartScreen Filter on Microsoft Windows might give a warning during the installation. For more information please check our Documentation.

(2)Use a program like md5sum to verify. This should come preinstalled on most Linux systems. On Windows systems, open a powershell and enter Get-FileHash .\windows_x64_64.exe -Algorithm MD5. On macOS systems, you can use md5 in the terminal.

(3)For macOS, also a simple self-extracting archive is available, which you can download here (x86_64) and here (arm64). Note, that this archive does not contain GAMS Studio. The md5 hash for this download is ca135a64f38cb62f88a958b298b1e53f (x86_64) and df669c032b4abdb83dce2ead45d4a705 (arm64), respectively.

To deliver GAMS with the best performance we are using the Amazon CloudFront web service, a global network of edge locations for content delivery.
