I have installed the SDK that came with Avante 10.4 on a PC.  I am using some legacy software to create an LFImageEnable instance and then do a search.  This works great - it displays the item searched for in the client, but then it returns error code 1426 with the message 'OLE error 0x80020010 : Invalid callee'.   Does anyone know how to get rid of this message ?
