Hi all!
I can’t install the German language, after clicking on the download button, I get the answer:

Downloading...
Unzip failed

How can I fix the problem?
Thank you!

Download manually and re-zip.
There is small bug in current osclass version.

Thanks for the answer. I did as you said and while loading the language pack it gives an error:
