Running Benders on Test_Case on 0.13.0

[damanhab]

I have run the benders command on the test case provided with AntaresXpansion as follows

solv <- "C:\Program Files\RTE\Antares\7.0.1\bin\antares-7.0-solver.exe"
SSS <- "C:\Users\Administrator\Documents\R\win-library\3.6\antaresXpansion\testdata\test_case"
setSimulationPath(SSS,simulation = 0)
benders(solv, display = TRUE, report = TRUE, clean = TRUE,
parallel = TRUE, recovery_mode = FALSE, ampl_path = NULL,
opts = antaresRead::simOptions())

I get the following error:

--- ITERATION 1 (complete iteration, 156 simulated weeks) ---
ANTARES simulation running ... [done]
Solve master problem ... [done]
Error in read.table(paste0(tmp_folder, "/out_underestimator.txt"), header = FALSE) :

In addition: Warning message:

Have you installed AMPL and a solver on your computer?

No I was not aware that they were needed to be installed on my computer.
I have amplr (ampl API for R) installed. and have set ampl_path = path of ampl.exe (C:\Users\azizb\OneDrive - UNSW\2020 - T1\Antares\amplide.mswin64\ampl.exe)

this has returned the following error
Solve master problem ... Error in solve_master(opts, relax_integrality, ampl_path) :
master problem returned the following error: Cannot invoke cbc: no such program.
