We're trying to add the Excel Add-In PLDRILL.Connect for a client. We can find the add-in, but get the message ""C:\program files (x86)\Common Files\BIComponents\PLDRILL.dll is not a valid Office Add-In"". Does anyone know what step(s) we might be missing? Our ultimate goal is to get the ""Report Tools"" functionality turned on, and we believe this PLDRILL file is the answer.
