I assume, there is windows partition (FAT32 ?) mounted at /mnt/win_g.
FAT32 does not support setting of some attributes specific for other flesystems (like permissions, owner, group, dtime etc). Try to move PlaneShift_CBV0.3.010.run to /home/maxim and run it from there.
Also, give /home/maxim/planeshift as the target installation directory.
Do You start instalation as root (by using \"su\" for example) or maxim ?
I\'m asking, because TMPROOT is set to /root/tmp ... And it should be /home/maxim/tmp ...
Try to run it as user maxim.
EDIT: Erm... I just thought... If that partition (/mnt/win_g) is NTFS partition, everything is clear. Linux cannot write to ntfs filesystem... in this case move/copy the .run file to /home/maxim too.
