I have two (feeble) suggestions:
Before re-installing, make sure you manually delete all CTP2 files first,
including files in other directories that you may have installed to.
Secondly, your system should be perfectly capable of handling the max install options. I have a sneaky suspicion that your problem has something to do with the Japanese version of windows. Even though other games work with this version, Activision will find a way to crash.
If you still get the same problem with the english version of windows, then you can at least eliminate one cause.
Good Luck.
