After installation, the package may need to be activated (and remember to activate AUCTeX too). If preview-latex is installed via the Emacs package manager (ELPA), activation should be automatic upon installation.
The usual activation (if it is not done automatically) would be
(load "preview-latex.el" nil t t)
If you still don’t get a “Preview” menu in LaTeX mode in spite of AUCTeX showing its “Command”, your installation is broken. One possible cause are duplicate Lisp files that might be detectable with M-x list-load-path-shadows <RET>.
