The Current version of the Daz Install manager should allow you to set a path for Poser 11 - click the gear icon to open preferences, then go to the Applications tab and click the + button to add a new application, set it to Poser, 11 (or 11 Pro), 64 or 32 bit, and then click the ... button to set the path. If that si done try setting an application as Poser pro 2014, and use the path to Poser 11, but I don't think the DSON Importer is flagged as Poser 2014 or earlier only.
