DAz's installers only run once on my system before their deleted. Like the others I point them towards a empty folder with a fake poser.exe in it. Once corrected and rearranged to my liking, I make my own zip files to actually install the item in my runtime folder. This has proven useful for both having archives without the criptic names, and installing something later on that's keyed to a certain file. Since my archives have all the path information stored in them, it's easy to extract just that file into my fake poser folder and then delete it back out once the new item's installer has been run.
