TCUP 5.9 Installing

[Abyss]

Hi guys, i'm trying to install TCUP 5.9 - currently running 5.7.

I change language to English and the installer displays the following

Uwaga: Aby móc zainstalowac program TC UP musisz wpierw odinstalowac starsza wersje. Zainstalowana wersa: 5.7.0.1029.

I have NO idea what this about - it's in Polish

Any ideas on how to get around this problem ?

Thanks for your excellent work - keep TCUP alive forever.
