Error "Unable to load word breaker for locale 0. Error code 8007007e." with search service application.

I recreate the Search service application and the default Content source stayning in the 'Recovering' status.

The log give multiple error 'Unable to load word breaker for locale 0. Error code 8007007e.'

The default language is English and the reference in registry for word breaker dll is naturallanguage1.dll but I found only the naturallanguage6.dll.
