SYMPTOMS
When a Component Object Model (COM) component is installed in COM+ as a library application and includes the following features:  Two interfaces (IXXX and IYYY) that are defined in one type library file named YYY.tlb. A third interface (IZZZ) that is defined in a second type library file.  IZZZ is derived from IYYY, and the IDL file for the IZZZ interface contains the following code: importlib(&quot;YYY.tlb&quot;); 

you may receive an Access Violation when the client application uses the IZZZ interface.
