Changes made on the Trimble Civil Product Services (TCPS) server are causing Tilos to fail (not crash) when you try to change your license method to Named User. Tilos stays in the current mode without giving you feedback.
To fix this issue, replace a single file in your installation folder using the steps below.
Note: The installation folder normally has restricted access. You will often need Administrator rights to copy files into it. For existing installations, you will be asked to overwrite files. The files can be overwritten.
