I am having the same problem. I have spent hours researching this problem with no solution as yet.  

Hi, all -

SupportAssist will not install.

Message,  "We ran into an unexpected problem."

"Suggest you restart your computer and try again."

Well, I've done that many times. No help!

Can someone please provide a workaround? 

Or, maybe a Dell Tech can call me and walk me through

the proper installation procedure?

Thanks . . .
