Office 2000 SP1 patch file missing

[Steven]

I recently installed a new hard drive in my system that
copied the contents of the old drive. The old drive was
crashing. Now i can't do any updates to Office 2000
Professional or remove the program either because the
data1.msi and data2.msi files are invalid. I'm running
Windows XP Home edition. Also using the windows clean-up
utility doesn't work either. Any suggestions on how to
fix this?

Thanks,
Steven
