Please refer to the Windows Installation Notes or the UNIX Installation Notes for more information about the necessary steps to setup a GAMS system. The complete system documentation and release notes can be found online. Please note that a current license file for Windows will work both under the 32bit and the 64 bit version. It will not work under Linux and vice versa.
Without a valid GAMS license the system will operate as a free demo system with these limitations:
The GAMS log will indicate that your system runs in demo mode:
