How to batch run failed tests for the second time?

don't know about such feature.

I would suggest you to:

1. run TestComplete

2. at the end of test run export all results to xml files

3. parse xml files and check if there are failed tests

4. extract failed test projects/routines

5. rerun Testcomplete from command line. E.g., TestComplete.exe /t /p /s/ p:"project_name"

Thx, it resolve my problem.
