Dell SupportAssist 4.1 fails to download install error

Tried to install Dell Support Assist 4.1 on Latitude 7490 and get a failed to download error.  Watched the Dell support video to delete PCDR etc. out of Program files / ProgramData to include the registry.  Also tried the Microsoft tool to uninstall, the support Assist is no longer in the Add/Remove or installed and still get the issue of Failed to Download on install.  Dell command 4.1 will also not install, "wizard was interrupted" and could not be completely installed
