How to close runtime error popup in testcomplete and continue execution

I am designing a script using python in testcomplete. During overnight executions of around 100TCs the execution stops due to runtime error popup in testcomplete. How to close this pop-up and continue the execution by failing the test case and moving to the next? 

Code example: 

try:

------

-----

except RuntimeError as e:
errorCode = e
Log.Error(str(e))
Log.Error("Runtime error has occured")  #custom message to be logged
return str(e)
finally:
#Close browser before moving to the next test case
close the browser
