Overwriting log file - command line

How to force test complete to overwrite test results (Log file) when starting tests from command line ?

I tried to use exportLog parameter but each time it requires non-existing log file name. How to resolve it?

My command line:

TestComplete.exe "C:\[path to project]" /r /p:ProjectName /t:"Group1" /exportLog:"C:\TestLogs\Log.html"
