I'm fairly computer savvy and was able to follow the directions in the package to install them. I've read some of these reviews and am appalled that some of these people couldn't figure out how to install these.
I've installed about 3 or 4 different sets of disks and dell disks are by far the easiest. I was able to get them installed in about 2 hours and have everything up and running and installing updates.
Keep in mind once you get the disks installed you need to install virus protection that will work for your machine. These guys sell virus protection which is some sort of lifetime protection software that I decided to buy. It turned out to work very well so far. Its only been about a month but my machine is still running like new.
If you're able to read, you should be able to install these disks. Don't listen o these other idiots on here.
