Greetings dell-robert p! After reading some forum posts about the same issue that I have, I've seen that even they have installed the latest version, the problem still exists. However, the solution I've found worked pretty well. All I did was rename a file as stated here: "Went to C:\Program Files\Dell\SupportAssistAgent\bin\Resources\New-Dell-Logo-White-Small.png and deleted -Small. Should look like New-Dell-Logo-White.png."   and it started working again. 2.2.1.23 is the SupportAssist Version that I have btw.
I have a Dell Inspiron 5570. Earlier today, i ran SupportAssist to optimize my laptop and then after an hour I opened it again then suddenly it's stuck at loading until it says "not responding" Help please.
