Click on the Publish icon.
The Publish command creates a read-only, protected version of a project that is suitable to be deployed in the field.
When the Publish command is executed, a new Project file (with extension "trun") is created with the version number selected. The Published Projects ("trun" extensions) are similar to the current project (".tproj" extension) and can be opened only in read-only mode. This provides you with a safe backup version of published applications.
