You don't need support assist to install any driver updates--only for the scan of your computer, which you don't need. You most likely don't even need any driver updates. Your Device Manager has the current drivers. [URL] Skip the scan which asks Support assist. Just use your service tag or your model name and number. Support Assist is not a subscription. It's free to all Dell users. But you really don't need it to maintain your computer. 
Hello, I purchased my Alienware Gaming PC last December. I had a year of Support Assist (premium?) included. I haven't been using my computer much over the past 4 months due to work and school. I want to know one of two things. Since I know that my subscription to Support Assist premium has already ended, why am I completely unable to find the application on my computer? I get on Dell.com, detect my PC and then it says "You need Support Assist". I never uninstalled it. I click download because, hey I want to reinstall it so I can update my drivers. It downloads the set up. I run the set-up and it claims "Installation cancelled- you already have the latest version of Support Assist." Repeat over and over again. Do I need to buy it somewhere else first?  That's my first question. My second, and possibly more important, question is how can I manage my CPU without it? I tried to update drivers on Dell's website and-would ya look at that- I need to download Support Assist. Any help is greatly appreciated.
