There is an annual Maintenance and Support Program for SketchUp 2013 and beyond, within this program you’re entitled to free upgrades if a new version comes out and to email support or phone support for installation related issues. You can read more about the program in our Knowledge Center here.

Thank you for your answer jody,i did´nt know about that.
