In addition to this, regarding your concern about the requirement to close the "VMWP application", it's possible that this application is running in the background on your system and interfering with launching the exam process, it's essential to ensure that all background processes are closed to avoid any potential disruptions during the exam.
To address this, we recommend thoroughly checking your system's background processes and applications to identify and close any instances of the VMWP application. You can typically do this by accessing your computer's Task Manager or equivalent system monitoring tool.
