When i say "does not run" it means that the software generated an
error " windows have encountered an error" and the software just shut
down. The strange thing is that i have tested the same software using
p2 (350mhz) on 64 MB ram with win 98 se upto p4 (2.4G) on 512 mb ram
with winxp pro and there is no problem at all, all of them have 1
cpu. But when i test with p4 (2.6) HT with 512Mb ram, winxp pro, an
error occurs.

I just dont know why.
