Quote - It also remembered mine ... and I'd uninstalled both 4.0 and the CMS before installing 4.5. Should have been a clean slate, more or less, but it wasn't. That makes me wonder if it's not somehow picking up "leftovers" that are confusing it.

 

Daz Studio is a 'dirty' app, even if you uninstall everything, lots of stuff is left behind, in the registry and the 'Applications' folder.

the only way to get a totally clean install is to manually delete all relevent entries in your registry, and also delete any files left in the 'Applications' folder.

preferences are usually found in the 'Applications' folder ,  serial registry etc is in the Windows registry
