SEP installation problem

Hi

i cant install sep on my Clients , installation complete with rollback.

i use latest version of sep (12.1.4.1b) and i tried push install , package install , unmanage package install with no hope.

when i use 12.1.1 package some clients installed sucessfully but still most of them  getting rollback , also i use fresh install of windows but nothing changed.

Clients :Windows xp sp3 - Windows 7 sp1

SEP : 12.1.1 - 12.1.4.1 b

SEPM 12.1.4.1

install log is attached to this post.
