My money wouldn't ever go to Dell's software service until I talked to someone who had experience with them. We've already got mountains of evidence that their hardware support team is doing well to determine where the power switch is on your laptop, would you want to pay extra for that same level of support on your software?
Without even calling them once, I'd bet good money that virtually every software call they handle goes like this: "uninstall the program, then reinstall the program." Advanced calls probably go like this: "uninstall the program, delete the directories it was in, then reinstall the program".
I'd get a printer.
