ignore it. SA is very buggy recently. just see the list of reported problems here - [URL] had the same for some time, but now SA dosent even run the check for drivers - appeared out of the blue.  
Today I came home to a new version of SA (SupportAssist) being installed. After restart the fans of my 2014 17 R1 were at their max RPM until I opened Dell SA. After this it checked for new available drivers and I'm now being prompted to install OLD drivers that are not compatible with my system? I confirmed same on Dells website, see image = [IMAGE]  
17 R1, SA install OLD drivers?
