TSUIN0101 The integrated tool FileCompare with the ID {0} must have two modelled file input parameters unless it is modelled within a mass processing action with two selected elements, in which case one file input parameter is required.

A "FileCompare" integrated tool was not properly modeled.

Model Administrator Response:
Either model the "FileCompare" tool descriptor with two file input parameters and use it within a single processing action descriptor ("MassProcessing = false"), or model a single file input parameter and use the tool in a mass processing action descriptor ("MassProcessing = true").
