Hi @DonnaMolinari
That's right. The steps above don't work and never will because:
1. This discussion is 2-1/2 years out of date.
2. CS3 is officially DEAD. Adobe discontinued all support for it.
If you had upgraded to CS4, CS5 or CS6 when you still had the chance, you'd be able to use your software. But since you didn't, there is no possible way to re-install your 13 year old software. Suggest you keep using CS3 on your old laptop for as long as you can. Get modern software for your new equipment.

Beware of fake Adobe reps who may contact you privately offering to sell you software or take control of your computer. It's a scam, run away! Creative Suite is not legally sold from any vendor, retailer or country.
