installer lacks gnupg component to be install


i have downloaded gpg4win-light-1.0.8.exe. i check the md5 and it was ok.

when i install, how come, the gnupg component to be installed is lacking, or not highlighted?

pls see pic


when i ran the program after installation, it says that " invalid crypto engine". does this mean that this software is not performing the encryoption as i thought it is.

pls. help im new to pgp or gpg.
