The problem is they have the same package name because they install to the same name folder, but I have solved this by changing my source folder names and unchecking "include root". After working around some additional quirks, finally got it working the way I want. Packages must have both different identifiers AND different package names. Would be nice if you could actually specify what your package should be called. ----- Original Message ----- From: "Karl Kuehn" <kuehn.karl@gmail.com> To: "Andrew Peckover" <apeckover@pgmusic.com> Cc: <installer-dev@lists.apple.com> Sent: Monday, May 04, 2009 12:49 PM Subject: Re: Prevent receipts from getting written?? I have a number of installers that install files to the same folder. The problem is, each install I do DELETES all of the files installed by the previous installer!! I think this is because they all install files to the same folder. I can't change that part of it. If I delete the receipt from the previous install, the problem doesn't occur. So, can I prevent receipts from being created at all? I can't believe that an installer would automatically delete files from a user's computer, with no option to prevent it... My guess is that all of these installers have the same "Package Identifier". I got stung with this when a couple of packages (in different mpg's) had the same identifier. It though that one was an upgrade of the other, and so cleaned out the "old" files for me. If you use full reverse-dns names for each package, and make sure that you can never have name collisions, that should take care of that problem for you.
