STAAD.Pro CONNECT Edition is a sophisticated application which can operate using one or more licenses that unlock various capabilities.
When STAAD.Pro is launched, the application will present a message dialog that will report which licenses will be used in the session.
If any of the capabilities you require is locked with a license not displayed in the message box or there are licenses displayed that will unlock features that are not required, then the licenses that STAAD.Pro will use can be redefined by selecting those that are required by clicking on the Configure Licenses button.
