Thunderbolt Driver for Latitude 5400

I am trying to install/update the following drivers:

service utility for firmware updates for Intel Thunderbolt controller: Intel_TBT3_FW_UPDATE_NVM46_D77Y2_A05_4.46.135.007
driver for Intel Thunderbolt controller:
Intel-Thunderbolt-Controller-Driver_TBTB4_WIN_1.41.1335.0_A14_01

I always get an error message and an error file, which I cannot understand, unfortunately. Can anybody tell me what is going on? Unfortunately I cannot upload the error files.
