Please find the attached file, Why I can't calculate the volume for any object? This message does appear when I use the Mac or Windows.

Do you mean to say you can calculate the volume in Linux but not in Windows/Mac? – Atekihcan Sep 06 '17 at 09:47

This error will be generated only if the mesh is not watertight, i.e. either the mesh has some boundary edges (holes) or some non-manifold edges.
Try with some different models to confirm. For example, generate a sphere in MeshLab (Filters -> Create New Mesh layer -> Sphere) and calculate volume.
PS: You can remove non-manifold edges in MeshLab and close the holes to make the model watertight.

"One thing to keep in mind is that duplicate faces within a mesh will affect the calculation of volume and moment of inertia."
If you have this situation, it can also contribute to the problem.
