You should be able to find it on the internet. On a new computer, it's best to install such things using the CD or the downloadable installer.. Copying such files over from a separate computer usually doesn't get the job done correctly.
Hope this helps.

I bought a computer in 1999 and ran it happily for more than 10 years using Windows 98. However, nothing lasts forever and I eventually had to buy (recently) an AMD which has XP installed because some programs I need won't run under higher versions of WIndows.
So one of the first things I wanted to do was get StarCraft Broodwar running. So I dug out my old CDs to install it and lo and behold they were too scratched to be usable. Accordingly I downloaded the programs and installed them on my computer using the original serial numbers from my original CDs.
The download also came with a patch to update it to version 1.51 (I think) but the version on my computer is 1.62. Which files should I copy from the old computer to the new computer to bring it to the latest version or can I download the patch on a USB and take it home or how does that work?
