There are 2 types of Relevance statements.
Sessions Relevance is ran against the IEM Server and has objects like BES Computer, BES Fixlets, etc.
Client Relevance is meant to be executed on individual computers, with objects like Registry, File, etc.
The statement you have above is a Client Relevance which and it will not work in the Session Relevance Editor in the Excel Connector.
