The PC/win version has a problem. I tried to download an unpack it 3 times. Every time it tells me "the archive is damaged" and the unpacking stops.

I've looked into it. Assuming you're using Windows and not Linux and getting the same error as I am about not being able to copy librenpython.so you should be OK to skip it as that's a linux library that Windows won't make use of anyway. If you're on linux - that's where it gets a bit trickier for me to trouble shoot blind.
If you're getting a different error than me can you provide me with the following information to look into it:
OS
Extraction Tool used
Exact error message
What Antivirus are you running?
