Trouble Starting Classic mode

Im having a problem getting into classic mode from tiger. When I try to open a classic app. or go in manually from the system preferences it says that i need to select a volume on the hard drive and that it cannot find a mac OS9 system folder on the startup disk to use. How do i install this classic support. Any help would be great, thanks.

I Classic is installed you should have a folder on you hard drive called Applications (Mac OS 9). Also older DIVX QuickTime plugins stopped Classic launches.
