Hi,
I found this reply from support team, have implemented same and till now not faced issue.
There is timeout associated with TestComplete (or TestExecute) attempting to communicate with its TCHookX64 helper process. The timeout was made configurable in a patch to version 11.10 and as part of the base product in version 11.20. There are two timeouts . . . one for when TestComplete (or TestExecute) is started normally and another for when it is started in Silent Mode. For more information on Silent Mode, see https://support.smartbear.com/viewarticle/69415/ "TestComplete Command Line" The normal and silent mode default timeouts are 5 and 30 seconds respectively. The following examples show how to double those times for TestComplete and TestExecute. (In the examples, the angle brackets are not part of the .REG files.)
still you face same problem :
Try increasing the NormalModeTimeout.
After increasing Timeout we are not facing this issue till now and will update if we find it in future.

Nethra
