Dell XPS 27 Will Not Install Support Assist

[JefD]

     When I go to the support page for the XPS 27, it recommends that I download Support Assist.  But when I download it, and click on it, I get a Windows error message saying it cannot find the specified file, or that it does not exist.  The same thing happens if I go directly to the Support Assist download page.  The download exe does appear on my computer, but apparently it does not contain a real file.  Can anybody provide insight on this issue?  Thank you.

You might want to re-post this in the SupportAssist forum, and be sure to mention the version of Windows you're running, and if it's Win 10, is this the April'18 Update (build 1803)?
