I have no idea what happened, but SupportAssist is all messed up on my Inspiron 3583. Tells me that there's an update available, and when it goes to install it, it instantly fails. Tried installing it manually, and it fails as well. Launching SupportAssist multiple times afterwards results in a "We ran into a unexpected error message". Tried uninstalling and removing leftover files and registry entries per advice on several other threads, only to make matters worse. Almost every direct link to the SA installer is broken. Those that work are a complicated MSI package with no setup interface. Eventually restored Windows from a backup image to revert my changes back. Same result.

Also affected is Dell Update, which now throws an error upon launching, stating that the Dell Client service is disabled, which I did not disable myself. After re-enabling the service and selecting automatic, Dell Update works, that is, until I restart my computer, which it then the service disables itself again. Last time I ran Dell update was a week ago (Jun 21) and experienced no issues at that time.

Seriously Dell, why is it so difficult to update, install, or uninstall SupportAssist? Please make it simple and less complicated. Also, you need a more helpful error message that this...

A description of the error would be nice for troubleshooting, rather than a vague unhelpful message that tells the user nothing. If that was the case, I'd probably wouldn't be here writing this post.
