The installer itself is / can be set to / Dutch (NL) language, but the installed system Application Language by default is English. I can register my serial and sign in with Adobe. All is happy - but in English.
I want Dutch language, as advertised by Adobe.
According to Acrobat instructions, I have to edit the setup, and then drop down the Language box and select the language i want to install. This does not work: only English is visible.
Also, I already tried to modify the installer itself with the Acrobat Customization Wizard, enabling all languages. Same result.
