Application language problem - Adobe Reader XI

[Kawa29924926bvy8]

Hi
After the recent update of Adobe Reader XI, my language changed from Polish to English. I can't switch back to Polish again

What I tried
Polish language is set in the preferences
When I click on the icon + ctrl select Polish does not change my language
Re-installation did not help anything.
Win 10 is in Polish language. Changing the language setting what is the system language also did not help
The installer was downloading automatically and using manual selection
I have no idea what else I can do. Does anyone have an idea how to fix it?
