Installing security update 2009-001

[toonz diggler]

I keep getting this error

"You cannot install Security Update 2009-001 on this volume. This volume does not meet the requirements for this update."

Any ideas?

What volume are you trying to install on? What version of OS X is it running?

Are you fully patched up? Try running Software Update.
