Everything had been working fine on my system. I was originally able to install programs, but ever since I uninstalled Doublecommand (not sure if thats the reason) I am unable to run installer packages. I can install programs that install themselves by asking you to drag the file into the apps folder, but when the installation process involves an actual install package, the process stops at the "Installation Type" step after I hit Install. I then tried running software update and the same thing happens after i hit "Install", it just hangs there like its going to start and doesn't do anything, and I can then hit "install" again and go in endless circles. I also tried updating to DellEFI 1.07 and it would give me error code -60008 Could not install extensions." after it tried to install each option. What gives? Any ideas are greatly appreciated.
