Problem in langage setup and company preferences

[barbarian]

What must I installed if my OS is Windows and where can I get it?

For the company preferences, it seems the pattern attribute in every input text cause the problem, so I just delete the attribute and it's working.

Thank you for your answer.

You need to have the language installed on your system for this to work. Then when you change the language, sometimes you have to logout and back in again to get it to work.

On the company preferences issue does the page get sent (do you see the browser refresh) and do you get any message on the screen. Normally it stays on the page but gives you a success or error message.

Thanks
