Thunderbolt Controller Firmware Won't Update

Question

Hi there, I have a Latitude 7490 that is on the latest BIOS version, and all the updates are applied through SupportAssist except for the Intel Thunderbolt Firmware. Every time I try to update it I get the error 'The Intel Thunderbolt Controller Driver needs to be installed or updated before the Thunderbolt firmware can be updated'. I have tried it both unplugged from the docking station and plugged into the docking station, and have made sure to enable the Thunderbolt Service in Services so it's running when I apply the update and it has made zero difference. I have tried uninstalling the Controller Driver, restarting, installing it again, restarting, and attempting the firmware update and still get the same error.  When I start the update, it says my version is 2.0B going to version 46.0. I have tried other firmware updates and didn't have any luck still. Please let me know if the controller is broken or if there's anything else I can try. Thanks!

I have the same issue on two different Dell Latitude 7490's.  Both have the latest Thunderbolt controller software installed, 17.4.79.510 A12, and both are running the latest BIOS, 1.18.0.  I have also tried older controller firmware updates, and they give the same error message.

These troubleshooting steps in this link here should be help with this. From what I can tell this looks to have resolved the issue.

The dock is running the newest firmware, updating the dock was what caused it to dysfunction           After the update the dock sometimes works but most of the time it does not.

I've gone through every thing in that link with the exception of enabling Thunderbolt in the Bios as its grayed out. I assume that because my 7480 doesn't have it.

Is there any way forward to install this, or how can I get the Dell Command Update to not present this as being needed for my laptop.
