We mostly have WD19TBS docking stations in our environment and a handful of WD19TB docking stations.  Were using Windows 10 Enterprise 64 bit as our OS and we can't get any of our WD19TBS docking stations firmware to upgrade MST from version 5.04.06 to 5.06.03.  It just fails every time. 

Were on the current version of BIOS (Version 1.18.2) on a Latitude 5420.  The update is being run in an admin account.  I've also tried to run the executable in Windows 8 compatibility mode with no luck.  I've upgraded every driver on the laptop that can be upgraded but still no luck.

I thought I had stumbled upon a forum that the docking station firmware can only be upgraded using Windows 10 Pro 64 bit and that doesn't sound right because their has to be thousand of companies using Windows 10 Enterprise that need to upgrade the docking station firmware in order to fix bugs.

Any ideas because I've run out of everything to try??

Note:  Were able to run the firmware update successfully on some of the WD19TB docking stations which doesn't make sense.
