CLSIDFromProgID error resolution

Top  Previous  Next

You have this usually:

 

   CLSID InvAppClsid;

   HRESULT hRes = CLSIDFromProgID (L"Inventor.Application", &InvAppClsid);

   if (FAILED(hRes)) {

       pInvApp = nullptr ;

       return ReturnAndShowCOMError (hRes,L"ConnectToInventor, CLSIDFromProgID failed") ;

   }

 

Which may fail with this error:

 

ConnectToInventor, CLSIDFromProgID failed

Error   = 800401f3

WCode   = 0000

Meaning = Stringa dell'interfaccia non valida.

 

This could be that you are running the compiler as administrator and Inventor as normal user.
