I suppose this might be not the very best English, but it’s still English.
In many (technical) contexts there is a need to use something like
‘non-updateable’ as an adjective. Or as a value of an option.
And in technical texts it’s not a great surprise to meet phrases like:
no updatable installation of package
Which version do you prefer (:)) :
updatable or updateable ?
no updat(e)able [size=84](by the way, this is a value of an option in some software applications. Including Microsoft products :), if I’m not mistaken. )[/size]
