Installer-dev mailing list (Installer-dev@lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/installer-dev/site_archiver%40lists.a... I have two install packages made by PackageMake 1.0,one of two is a update package in which the application has higher version info. I install the newer package A.pkg firstly,and then delete it from my computer.Then install the another package B.pkg. During the installation of the second package,a message is given by Installer which is "You cannot continue.There is nothing to install.".Then exit the installation. This problem doesn't occour on 10.2 or 10.3. There is a known bug where it tells you there is nothing to install, rather then not allowing you to install in the first place. In package A.pkg's info.plist,key of CFBundleShortVersionString's value is highter than that in package B.pkg's info.plist. Delelte the my application only, don't delete /Receipt/A.pkg.After do this ,if I modify the value of CFBundleShortVersionString in "/Receipt/A.pkg/Contents/ info.plist",make the value lower than B.pkg's,the installation will work successfully.And execute it as an upgrade. Does Installer determine whether to install or upgrade by CFBundleShortVersionString's value in file "info.plist"? Is it a new feature of Installer on 10.4? This is not a new feature in 10.4. What is new is that we use the CFBundleIdentifier as a unique identifier (or the package name, if you did not use identifiers). So if A.pkg and B.pkg has the same CFBundleIdentifier (they shouldn't, considering they are different things all together, right?). As for CFBundleShortVersionString, it was used in previous system versions as well. This email sent to ryanc@apple.com This email sent to site_archiver@lists.apple.com
