I've uninstalled. I reinstalled. I tried to install from a disc burned from another computer. I've downloaded it via different browsers. Every time I get an error message "Adode Reader could not install correctly. Adode Reader was unable to install and must quit."
First thing to try is to install as a different administrative user. If
that fails, then try to fix permissions. If you have it, try running
Applejack and let it clear your cache's. If that doesn't work, I'd try
to install as root. If that fails, I would recommend an archive and
install of the OS.
