Provisioning Windows Driver Kit fails due to unclear error

Question

I am trying to set up a "target" PC for Windows kernel driver deployment and debugging, and have meticulously followed all the steps here and here.

I am at the Provisioning step now and am trying the automatic Provisioning in Visual Studio, like so: 

It fails with the following errors, however:

Upon inspection, it is clear that the issue is the following command:

$KitRoot$\Testing\Runtimes\TAEF\%PROCESSOR_ARCHITECTURE%\MinTE\te.exe "%SystemDrive%\DriverTest\Run\DriverTestTasks.dll" /select:"@Name='DriverTestTasks::_ConfigureKernelDebugger'" /p:"DebugTransport=NET" /p:"TestHarness=ERT" /p:"NetHost=169.123.456.789" /p:"TestHarness=ERT" /p:"NetPort=50000" /p:"TestHarness=ERT" /p:"NetKey=xxxxxxxxxxxxxxx.xxxxxxxxxx.xxxxxxxxx.xxxxxxxxxxxx" /p:"TestHarness=ERT" /p:"StartPolicy=Active" /p:"TestHarness=ERT" /p:"IgnoreUserModeExceptions=0" /p:"TestHarness=ERT" /p:"SuppressReboot=1" /p:"TestHarness=ERT" /rebootStateFile:%SystemDrive%\DriverTest\Run\DriverTestReboot.xml /enableWttLogging /wttDeviceString:$LogFile:file="%SystemDrive%\DriverTest\Run\Configuring_kernel_debugger_settings_(possible_reboot)_00000.wtl",writemode=append,encoding=unicode,nofscache=true,EnableLvl="WexStartTest|WexEndTest|WexXml|WexProperty|WexCreateContext|WexCloseContext|*" /runas:Elevated

Also if I run this command manually on the target PC, it indeed fails, but it is clearer on what fails: it says it can't generate this output log file. If I run the following command (i.e. removed all output settings) it succeeds fine!!

$KitRoot$\Testing\Runtimes\TAEF\%PROCESSOR_ARCHITECTURE%\MinTE\te.exe "%SystemDrive%\DriverTest\Run\DriverTestTasks.dll" /select:"@Name='DriverTestTasks::_ConfigureKernelDebugger'" /p:"DebugTransport=NET" /p:"TestHarness=ERT" /p:"NetHost=169.123.456.789" /p:"TestHarness=ERT" /p:"NetPort=50000" /p:"TestHarness=ERT" /p:"NetKey=xxxxxxxxxxxxxxx.xxxxxxxxxx.xxxxxxxxx.xxxxxxxxxxxx" /p:"TestHarness=ERT" /p:"StartPolicy=Active" /p:"TestHarness=ERT" /p:"IgnoreUserModeExceptions=0" /p:"TestHarness=ERT" /p:"SuppressReboot=1" /p:"TestHarness=ERT" /rebootStateFile:%SystemDrive%\DriverTest\Run\DriverTestReboot.xml /enableWttLogging

So the question is: is there any way to make this work, either by fixing the real issue (no idea what that is), or by simply having Visual Studio call the same thing but without output files?
