Installation problem

I accidentally recently deleted part of my Office
software, and after I ran System Restore, it wanted me to
reinsert my disk in order to run installation.
Unfortunately, I don't have the disk anymore (I've looked
far and wide) and can't find the required DATA1.MSI file
anywhere on my hard drive. Any suggestions?

George Morrison,
You can try here for a replacement Office disk:

If this does not work for you, you will need to purchase a new copy.
It would be prudent on your part to store your software in a safe place.
You will need it in the future, as you have found....
