How can we run all the scripts in batch mode in QTP 9.0 ???
you can seek more information from help file with in QTP
Press F1 in the contents tab type Batch and then click on enter. Now from the top you can view the third one "Running a Test Batch" and then read it.
The issue what you have listed does not exist, works fine in my machine- stupid comment from the developer
Though the MultiTest Manager Utility is not recommended for versions above 8.2 by HP, I have been able to use it with QTP9.5 without any issues till now... much better option than the 'Test Batch Runner' Tool.
