Dragon UnPACKer creates HKEY_CURRENT_USER/DUP5.Packages key, this shouldn't be on such high level, I don't know for now when is it created, possibly during first launch. That key contains one empty key named DefaultIcon
Tested in 5.7.0
It looks like editing line 431 of DragonUnPACKer/common/lib_Utils.pas should fix that (I don't have Delphi so I cannot test it)
