This seems an improbable cause, as most of the PowerTools (if not all) have nothing to do with opening QVW documents or querying associative data. They're mostly intended to ease management of services and server data.

The same question has already been asked before, but maybe for good measure you should add yoiurs to the end of the discussion underneath Power Tools 1.2 for QlikView
