i test my problem
i check in 4 version OS win xp
2 different xp with sp2 (2 different cd)
1 os without sp
and last vers corporate xp sp2
key good but not work. so i think is not os problem.
Yeah i got the exactly same pc same error system wont accept the key ect, its not the OS gotta put it in single core for it to accept the key
Control panel > system > hardware tab > device manager > computer > (should say would kind of processor u got there)
It Should say something like ''ACPI multi processor'' for dual core
To change it > update driver > advanced option> dont search, I will choose the driver to install >
(now should have 4/5 options to change your processor change it to ''standard computer'' for 1 core
Now try put your key, make sure PRC chinese packs are done
Your system might run really slow because changing it to single core so soon as you put key in get windows xp disc and do windows repair
It will change it back to ACPI multi processor dont the do above way to change it back.. because if you do it that way somethings might not run proper so do windows repair with windows xp disc
