Hi again,
After discussing with the customer support, simply, for each remote machine install the Automated Testing Bridge executable whether you have TestExecute or TestComplete installed.
Therefore when configuring the bridge, the drop down list at the bottom "Run with" display the automation tool you have installed on the machine (TestExecute or TestComplete)
Leave some time for QACompelte to register the machine, and then go to Software Planner website, and find the remote host recently registered when create automated scheduled test.
Enjoy ;-)
