Hello, I have written one script to delete the files from Users home directory if exist. And I have added that script to post-Install script when i am making package for my application. The Application is not installing and i am getting error "Installation failed". And if I removed the part of Post-installation script and I again installed application. It installed successfully. but i was not able to see my application in destination directory. Now I am not able to install any package made by me. I am always getting one warning that is ".app is word writable".how can i resolve this warning. So, what do i need to take care while setting post installation scripts ? And If there exist my application in applications directory and i want to uninstall that application then what is the procedure to make uninstaller? Thanks.
