It's my understanding that when Process.Execute returns, Process.Running
is true. If it's False after Process.Execute is called then it has
already run and exited cleanly or uncleanly which can be checked with
Process.ExitStatus.

Some more info On TProcess can be found here:

See the "Reading Large Output" section on why it can be important to
read data while the process is running rather than waiting until the end.

Somebody please correct me if I said anything that's incorrect.

Regards,

Andrew
