When I start CIS_Setup_3.8.64263.468_XP_Vista_x32.exe on my Asus eeePC 1000H / XPsp3, it abends and I get the "Tell Microsoft about this problem " window.
CIS_Setup_3.5.57173.439_XP_Vista_x32.exe installs without problems.
Nothing obvious seems to be wrong with the 1000H as such. XP is working fine. Memory test OK. Installing and running Ubuntu/EasyPeasy without problems.
