Hey, thanks for the info. I found the page on the Dell website to download SupportAssist, so I downloaded and reinstalled over the version I had that wasn't working and problem solved!
I've performed a clean install of my Dell XPS laptop. After the install, I installed a few programs, then ran SupportAssist. I got the error message... 'We ran into an unexpected issue with SupportAssist. Restart your PC and try again later'. I tried restarting a few times but it still wouldn't work. As I hadn't installed many programs I thought I'd restore again in case something had gone wrong. After the 2nd restore, this time before installing anything, I ran SupportAssist Once again I had the same issue.  I'm really keen to get SupportAssist running to keep my XPS in optimum condition, so I hope someone is able to help me resolve this.
