backing up a program

[Ade007]

I am trying to back up some of my programs. However, I cannot find the program disc to one of my programs. I have my product key#. How can I save the program to a cd-r so that when I reload it on my computer, all I need to add would be my product key?

If you mean copy the installed program to disc and use that to load to a different computer or back to the old one, you usually can't as the setup file is missing. You would need that from the disc to load the program back in properly. If you have the product key, you should be able to get a replacement program or disc from the manufacturer.
