Change regional settings

I would like to change the regional settings, however I can not select other than Hungarian. I have downloaded US version again, but the user interface remained Hungarian. Thanks for the help.

You have to install LO again. Chose ‘Change’. Click open ‘Extra Interface Languages’. Enable the language(s) you want to be able to use for the UI. After installing you can change reggional setting for the UI. The Locale setting should list all available languages.
