Resolve
Correct SCM error
The POSIX application referenced in the Event Viewer message text was running as a Windows service, but a Service Control Manager (SCM) call to StartServiceCtrlDispatcher failed. For more information about debugging a service in Windows, refer to the Microsoft Web site (https://go.microsoft.com/fwlink/?LinkId=95087).
Verify
Because multiple instances of Psxrun can be running at once, it is best to verify Psxrun in Windows Task Manager not by checking on a particular instance of Psxrun, but by verifying that the specific POSIX process or application launched by using Psxrun is running.
To verify that Psxrun is running:
- Open Windows Task Manager by pressing CTRL+ALT+DEL, and then clicking Start Task Manager.
- On the Processes tab, select the Show processes from all users check box.
- Verify that a specific POSIX process you have started by using Subsystem for UNIX-based Applications is running.
If the POSIX application or process that has been launched by using Psxrun is indicated as running in Task Manager, then Psxrun is fully available. If the process is not running, critical errors are preventing Psxrun from being available.
