Simulation Failed

Hello,

I am new with solidworks.

I am trying to use the tutorial to learn about the simulation.

I am going to: Help>SolidWorks Simulation>Tutorials>Static>Analysis of a Part

Opening the file Tutor1.SLDPRT, going to the ready file, and clicking run I am getting the message:tutor1-Ready:Failed.

Going to Help>SolidWorks Simulation>Validation>Verification Problems>Statics, some cases are working fine but some others are presenting the same problem.

Somebody knows whats happenig? Someone have the same problem?

Thanks and Regards!
