We are getting an error when trying to install the QuickAdd.p[kg via SelfEnroll, This was working at one stage. I don't know what has changed to give the error on multiple computers when trying to install the pkg.
Error from system.log:
9/04/13 9:58:51.451 AM Installer[1501]: The Installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance.
Even recreating the QuickAdd.pkg has no effect.
