[emptyhead]

hiya guys...

I'm having trouble installing zoo tycoon 2 on my
computer.Everytime i try it gets to 73%,then i get this message
Zoo Tycoon set up encountered a disk error while writing
to the file c:\program files\microsoft games\ zoo tycoon 2\
sounds\B_TF_lop.wav.
Make sure that your hard disk is not full and that the file
is not in use.
I ran a disk scan and tried again but got the same message.

windows xp

sp2
intel(R)
celeron(R) cpu 2.50ghz
2.49ghz,512 mb of ram
Hope someone can help i hate to think i've wasted my money.
