the Daz installer puts a text file in ..ReadmesProductLists that lists what and where stuff got installed.   The Daz  installers could be better , like read a control file for default load values, but overall they aren't that bad.   I will concede that a group of zip files would be easier. 

The Daz installer content CAN be listed if needed. It requires a utility that isnt generally available though.  I wrote my own so I could catalog the installers.
