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 want my package to run only if a certain file does NOT exist. If the file does exist, I'd like the installer to fail and show a message. I've trying to use PackageMaker's requirements tab but when I try to run the package on a system that I know meets the requirements, it fails. Can anyone lend some wisdom?? Here are the lines from the distribution.dist that PackageMaker created. <?xml version="1.0" encoding="utf-8"?> <installer-script minSpecVersion="1.000000" authoringTool="com.apple.PackageMaker" authoringToolVersion="3.0.4" authoringToolBuild="179"> <title>Lingraphica 7.0 Upgrade</title> <options customize="never" allow-external-scripts="no" rootVolumeOnly="true"/> <installation-check script="pm_install_check();"/> <script>function pm_install_check() { if(!(system.files.fileExistsAtPath('/Users/client/PreviousJune10/ Startup.lca') == true)) { my.result.title = 'You have already installed this upgrade.'; my.result.message = 'It looks like you have already attempted to install this upgrade.
