Can't apply thunderbolt SP113453

[hainep]

After consulting with HP sales to ensure compatibility, I purchased a Thunderbolt G2 dock because my Dell dock that had worked for years would only output if one and only one display was plugged in.  Plugging in the second made both unavailable and Windows reports it could not find either.  Removed the old Dell from the system.  The new HP dock fails just like the old Dell (and has fewer ports).   

I have updated  Thunderbolt Control Prog, NVDIA G2 drivers and HP's version of Intel's UHD display drivers but I cannot apply HP SP113453.  It fails.

I can run USB, ethernet and one display through the dock and it is charging the laptop.  Both external displays are Dell E2417H, one using the DP, one using VGA.  This worked on Dell dock for years.  Until it didn't about three (?) weeks ago.  

I am running Win 10 build 19042 and BIOS Version/Date AMI F.31, 05/20/19.  HP Assistant says there are no updates required.

HP has few options for Thunderbolt G2 dock. None of them is compatible with your machine. Please check again on the following list (from page 39).

Huh.  Well... it certainly was useful to check with HP sales before I bought it so this wouldn't happen...  I can attach the chat but why bother, eh?  time to get money back.  I spent a day on this so thanks for saving me from flailing even longer.
