Question: Running MapleSim 5 examples

I have just started using MapleSim 5 and running the examples I got the following notification and don't know how to resolve it (to what options are being referred to and what is infolevel?):

Compiling...

(in dsolve/numeric/RunSimulation) unable to compile, please check your options by running with infolevel[ToExternal]:=1;

Simulation failed.

Please Wait...
