 A GAMS/​Gurobi-Link connects the GAMS Base Module to the Gurobi solver, but does not include a license for the solver. The Gurobi license needs to be purchased/​requested directly from Gurobi. A GAMS/​Gurobi-Link connects the GAMS Base Module to the Gurobi solver, but does not include a license for the solver.

 +There are two ways to solve GAMS models with Gurobi.
 +  - The "​full"​ **GAMS/​Gurobi-Link**,​ which requires two licenses:
 +     - A GAMS license with components GAMS/​GUROBI-Link and GAMS/​BASE ​ (to generate models beyond the demo limits)
 +     - A Gurobi license (you need to get directly from Gurobi)
 +  - The "bare bone" **OSIGUROBI** link which lacks a lot of functionality compared to the full GAMS/​Gurobi-Link. Using OSIGUROBI does **not** require a GAMS/​GUROBI-Link license.
  
 If you attempt to use the GAMS/Gurobi solver with a link license and you haven'​t set up the Gurobi portion of the licensing, you will get a licensing error with a message describing the problem. For example, with the 64-bit GAMS distribution 24.7.0 I get the following log output when attempting to solve the rotdk model from the GAMS Model Library: ​ If you attempt to use the GAMS/Gurobi solver with a link license and you haven'​t set up the Gurobi portion of the licensing, you will get a licensing error with a message describing the problem.
