how to unblock 'encrypt contents to secure data'

[trevster20]

i want to encrypt a folder but the 'encrypt contents to secure data' isnt
highlighted available to select the tick box. Any suggestions on how to be
able to select it?

It only works in the professional versions of Vista.

Which sucks.
