I have installed Gurobi and when I try to run my code I get the following error. 

File "C:\Users\kumudua\Anaconda3\lib\site-packages\pyomo\solvers\plugins\solvers\GUROBI_RUN.py", line 61, in gurobi_run
model = read(model_file)
File "src\gurobipy\gurobi.pxi", line 3571, in gurobipy.read
File "src\gurobipy\gurobi.pxi", line 80, in gurobipy.gurobi.read
File "src\gurobipy\gurobi.pxi", line 32, in gurobipy.gurobi._getdefaultenv
File "src\gurobipy\env.pxi", line 62, in gurobipy.Env.__init__
gurobipy.GurobiError: Unable to open Gurobi license file ' C:\gurobi950\gurobi.lic'
ERROR: Solver (gurobi) returned non-zero return code (1)
ERROR: See the solver log above for diagnostic information.

I referred to the previously posted questions and noticed a similar issue and has been advised to run the following command. So I tried that also and get this;

Error 10009: Unable to open Gurobi license file ' C:\gurobi950\gurobi.lic'

My licence is valid till Nov 2022 and cannot figure out the issue. Please advise.

  Hi Kumudu,

  A few things are mixed up here, it seems. You are running on Windows I presume, judging by the paths in your error message. Yet, the command you tried to run is using a macOS path.

  Can you please check whether there is a license file in "C:\gurobi950\gurobi.lic"? You may also try moving this license file to "C:\gurobi\gurobi.lic", instead.

  I hope that helps.
  Cheers,
  Matthias
