My Dell Downloads windows 7

First of all, please accept my apology if this question is not posted in the correct spot. It is as close as I could find. I need to download software from the My Dell Downloads site and burn them to a disc with a computer other that the dead one that the software is for. The problem is that I cannot find a way around the automatic registration. I need to be able to enter the service tag manually to get the correct software. How is it that I can burn the software with the wrong computer so that it can be installed in the correct computer? Thank you.
