Your first step in purchasing a commercial license is to contact Weavecentrix sales support.
A Weavecentrix Desktop commercial license is valid for a period of 1 year. Near the end of that time, you will be issued a reminder that the period of your commercial license is about to end. At the end of the period of your commercial license, you will no longer be able to use Weavecentrix Desktop unless you purchase another commercial license for a year.
