AMPL IDE does not work for cplex

[nys]

I've tried an example in using cplex via AMPL IDE Version: 3.1.0.201510231950.

Here is my commands:

ampl: model 'lp.mod';
ampl: option solver cplex;
ampl: solve;

Incorrect usage. Correct command syntax is:
   cplex [-i] [-f <commandfile> | -c "<command1>" "<command2>" ...]
Exiting
Error executing "solve" command:
can't open C:\Users\nys\AppData\Local\Temp\at2384.sol

The same command works well in ampl console as:

ampl: option solver cplex;

ampl: solve;

CPLEX 12.7.1.0: optimal solution; objective 0

0 simplex iterations (0 in phase I)

PS: it works also fine for other solvers as gurobi in IDE:

ampl: option solver gurobi;
ampl: solve;
Gurobi 7.5.0: optimal solution; objective 0

So, I guess that this could be a bug in ampl ide. Any suggestion? Thanks in advance!
