Missing Drilldown report for RDA

SOLVED

We are using Sage 500 ERP Intelligence Reporting 2015 with Sage 500 2016. From a Report Designer Add-in report, a user attempts to drill down to the transaction detail on an income statement account. But they encounter this error -

The drilldown report Report Designer Add-In-GL Transactions S500 1-0 required to perform the drilldown doesn't exist

Where can we get the missing addin report and install it? The RDA report used is based on Consol. Report Designer Add-In S500 1-3.xltx.

Thanks

John
