Hi, I've been getting errors every time I try to install a program update. I'm not able to install the latest Macromedia Flash Player, the Firefox update, or mac security updates. When I tried to install the security update and it failed, the error message mentioned something about permissions, which is why I think that may be the source of the other installation issues too. Does anyone know what I can do to allow the installations to work? I run a Mac OS 10.3.9 system.
