The Type Library file (TLB) describes the interface offered by a COM server such as Interactive Reporting Studio. Dashboard Studio uses the TLB to communicate with the services that Interactive Reporting Studio offers. In a standard installation, the TLB is located in the Windows system32 folder and is called brioqry.tlb. The Interactive Reporting Studio installer keeps the application and the TLB in synch. However, when non–standard mechanisms for upgrading are used problems may arise.
