If you haven't already, reinstall the game according to the large-print instructions at the top of the
second post in
this thread.
When it comes to the part with replacing the swkotor2.exe with the one from SecuROM, DO NOT overwrite the original .exe; just rename it. If the game still crashes right after character creation after completing the installation, try using the the original .exe instead of the one from SecuROM.
If that doesn't work, there is a link in that post that will allow you to contact SecuROM and request a new .exe.
If you're trying to use a crack; forget it. The KotOR2 cracks will not work on Intel mobile chipsets.
