How to avoid any popup during TC lauch

Hi



when i lauch TC(version 8.5) some times i encounter log file deletion error message. i get this even if i lauch TC in silent mode. but in silent mode  popups are suppressed while closing the TC only.

so i need a way to run TC without any popup from launch till closing. if any one gives me a solution then it would be of great help.



Thanks in advance,

Anand
