If you have access to another computer you could save the file from one

I have been using my PC with excel program for 3 years and when I tried to
open an excel spreadsheat today and it would not open. "Installation error:
file not found" appeared. File not found was SKU011.CAB and I have not been
able to reinstall as I don't have the installation CD as I bought the PC
second hand with programs on it. Can anyone help?
