Hi!
Thank you for the report!
Error is coming from the sub-application, usb_setup-*.exe, which is based on libwdi. Update tool application was not affected, and the process should entirely be success, if it has started (if the drivers would fail to work, Update Tool would not be able to connect to the device and start the update process). Attached log dfu-programmer.log confirms, that the firmware was validated:

/app/3rdparty/dfu-programmer/src/dfu.c:153: dfu_download( 0196E920, 6, 0493FCBE )
/app/3rdparty/dfu-programmer/src/dfu.c:188: dfu_upload( 0196E920, 1024, 03D49988 )
/app/3rdparty/dfu-programmer/src/intel_hex.c:625: Validating image from byte 0x2000 to 0x3FFFF.

/app/3rdparty/dfu-programmer/src/dfu.c:153: dfu_download( 0196E920, 3, 0493FD8D )
/app/3rdparty/dfu-programmer/src/dfu.c:153: dfu_download( 0196E920, 0, 00000000 )

The driver installing program is executed on each first procedure start on given Update Tool execution, hence it may show itself in the future runs. It will not influence the update process, but should not bother the user nevertheless.
