There is no link between the ActiveReports and the Hyperion FDM software.
FDM leverages ActiveReports as a 3rd party software and is built into FDM already. There is a designer and such also already in place in the Workbench. You can not 'upgrade' the version of Active Reports either. Also functions/APIs/etc. that are required to write FDM Reports will not be available inside of ActiveReports if you use their interface.
