SupportAssist will not update to 4.0. I get as far as "We're preparing SupportAssist to help you keep your PC running at its best." The 'spinning wheel' keeps spinning endlessly. I have Windows 10, fully updated. Cache/cookies cleared. Did a restart. Apps and Features shows 4.0.0.51819. Should I uninstall and then reinstall? I'm not tech savvy and, due to my computer's age, I'm no longer permitted to purchase Dell Software Support. Any suggestions would be appreciated.
