I am trying to deliver Flash 9 as an MSI-based app, but when attempting to
install I get an MSI 1603 error. I enabled MSI logging, and the logs
invariably start with "You must have administrator privileges to install
Flash 9..." and then simply list the MSI properties. We are using DLU
policies that restrict users to local Users group access.

I have tried adjusting the executable security level from normal user to
secure user, to unsecure user with no effect. I have also tried changing
the application properties from Install Only to Path to Executable with
parameters also with no effect.

I'm running the Zen agent.

Any ideas why I can't install in one of these manners?
