ispell-program-name is already defined in ispell.el. You probably want
to use setq here.

The above is the same as "C:/gnu/aspell".

Since you're supplying the full path, you don't really need to locate-
file unless you are unsure which of exec-suffixes applies.

(file-executable-p "c:/gnu/aspell.exe")

Should be enough if you find the behaviour of falling back on "ispell"
useful when aspell does not exist in that location.
