Collecting info for this system...
Operating system: linux
CPU Arch: x86_64
trying mojosetup in bin/linux/x86_64
USING en_US



PANIC
Initial setup failed. Cannot continue.


Error: Couldn't run mojosetup

I downloaded the game in German Version.

Despite this what file hash do you have: Otherwise maybe not enough free space?

Thank you for the answer!
that is what I have:
CRCsum="4284831924"
MD5="df65b32cf659b14e2614679d42051105"
TMPROOT=${TMPDIR:=/tmp}

I have 200 Gb free space

Your file hash is different. Which means, barring hardware problems, you have a corrupt/incomplete download. You need to download it again.

I downloaded the game again and i installed it!!
Next I got this ;(

The product page states that some packages must be installed prior to run the game. I think you could install them through your software manager.
