The installer installs essential files (LFO and base WAVs) into the admin’s AppData\Roaming\iZotope\Iris 2 folder. Simply copy that folder to your regular user account and it should work fine. Beware! There is a space in “Iris 2”. The plugin also seems to create a folder at the same level without a space….. don’t copy/move your stuff there, it won’t work. BTW. Microsoft’s ProcessMonitor helped a lot to identify where it tried to read those files from…. thx a lot to iZotope for wasting my time with debugging basic installation crap.
