I don't see the attached batch file.
My assumption is that the /exit is not being used on all lines in the batch file and, hence, TestExecute is not exiting properly.
For running multiple projects, that's what a Project Suite is for. Have you considered creating multiple project suites and then just including the appropriate projects in those suites? That might simplify things as well.
Not attached the screenshot - part of my batch file - rest everything is same as mentioned in the Testcomplete documenatation.
We are using different projects here. These differenct projects in different project suites.
