SolidWorks can register idle time with the SolidNetWork License Manager so that licenses that have not been used for a certain amount of time are returned to the free license pool.

1. In the SolidNetwork License Manager installation directory, create a text file:

   SolidNetWork_License_Manager_install_dirLicensessw_d.opt

2. Add the following line to the file:

   TIMEOUTALL seconds

   where seconds is a number greater than or equal to 900 (15 minutes), which is the minimum time allowed.
