"MacroMedia Flash

Flash player (+ Mozilla Firefox) no longer installs properly as of version 8.x. When you click on install_flash_player.exe it automaticallly installs the files to wherever it thinks you need them (without prompting for ANY interaction) - then its done. You can not do this as a non-admin account, and non-admin users no longer get the function of the installed flash player on the admin account."

Sounds to me that a limited account is... limited.
