Problem with Xcos

[Manuel Núñez García]

For the Technical Support Department of Scilab:

I have recently installed Scilab in my computer and I found a problem. 
When I want to run a simulation on Xcos of an electrical circuit I 
obtain this error mesage:
"A Fortran or C compiler is required"
I obtain the same message when I want to run the demos of electrical 
circuits. How can I solve this problem?

Thanks for your attention.
