SupportAssist missing and cannot reinstall

So last night I was going to run the Dell SupportAssist and when I was going to click on it, it was gone and than I searched for the answer on the dell community but nothing helped me so I am going to write here and ask my own since I can't find the answer. I did found something close to where I clicked on control panel > programs and when I right clicked it it said uninstall and repair and I click repair and it said it was missing when ever it was there so I click that and said something about it missing like kind of corrupted so than I decided to reinstall it so I uninstalled that one and tried to start the installer and when ever I did it said I probably lost connection to the internet with it saying installation cancelled when ever I did not get disconnected to the internet so how can I fix this.

I also have a windows 10 OS.
