install Mobile Sales in other languages?

Hello guys!

It was a long and hard way, but after some very long time my MSA 5.0 SP09 is working properly. But at least there is one thing that is not very fine:

Is there a possibility to install the MSA-Application(s) in other languages, e.g. German or French!?

If yes, how do i practise?

thanks to all in advance for your efforts,
