I just downloaded and extracted the HDF that was in the version from the url below.
http://www.amiga-storage.net/?page=Packs&file=AmigaSYS4_AGA.zipI made sure i had a Workbench diskset ready. (ADF files)
In the uae config i pointed to the HDF that i extracted.
Booted uae and followed the installation steps.
I could also have specified a more powerfull Amiga in the uae config.
Anyway its working. Hope you can have it up and running as well.
