Resolution:
To start a process you want to run in the foreground, create a utility that the TIB/Hawk agent can invoke with custom:execute and pass it the process you want to execute in the foreground. This utility will be responsible for setting all the permissions required to start and display the GUI application.
Custom: execute run in the foreground on a system wide basis by changing how the TIB/Hawk agent service is configured. Follow these steps:

Select Start--Settings--Control Panel, then double-click Services.
Choose the TIBHawk service and click Startup.
In the Service window that appears, click the System Account radio button in the Log On As panel.
Check the Allow Service to Interact with Desktop check box. All processes spawned by the TIB/Hawk agent will now be in the foreground.

When I start a GUI process with the method custom:execute in Windows environment, the process will only run in the background.How can I cause such a process to run in the foreground?
