How to avoid this popup using a switch from command line?(In TestComplete and TestExecute)
No, there is not. /SilentMode selects the default button in the dialog. I'm curious as to why this is a requirement for testing your application...

Your solution avoids the popup. However, I was wondering if there a way to override the default option in the prompt? Currently default is No, can this be changed to Yes during execution?
Unfortunately, no...
...now, to me, the question is... why can't the log files be generated? It seems that this message is the true problem... I'd be a bit worried if I couldn't generate the logs.
