Here is my solution to this issue:
1. Press Windows Key + R to open the Run menu
2. Type "gpedit.msc" and click OK
3. Navigate to Computer Configuration\Administrative Templates\Windows Components\Windows Installer
4. Edit the item titled Prohibit rollback and set its value to
Enabled
5. Click Apply and then OK to save these changes
6. Run the installer for the Surface Dock Updater and install (You will still get the error, just ignore it)
7. Browse to C:/Program Files/Microsoft/Surface/Dock Updater/
8. Run MicrosoftSurfaceDockUpdater.exe and follow the on-screen instructions to install the newest firmware to your Dock
9. Revert the Prohibit rollback flag back to "Not Configured"(make sure to apply changes)
The only issue with this method is that while it does allow you to update the firmware on your Surface Dock, it does not update the Surface Book**.**I am not certain of what functionality is missing because of this. However, the dock still works with the laptop (and in my case improved its usability).
