I have understood. Factorio has been extracted on ntfs partition.
When I have extracted it in ext4 partition, then the game has started.
Thank you very much!

Hello! I have downloaded demo, extracted, and launched with a mouse. But the game does not start.
Then I have tried to launch factorio with a console:
cd /media/newfag/WLT/MyFiles/Temporary/factorio/bin/i386/

> factorio
factorio: command not found

>./factorio
bash: ./factorio: Permission denied ...
