See Is a Windows applications running? File #9292 or you can use WMI

loLocator		= CREATEOBJECT('WBEMScripting.SWBEMLocator')
loWMI			= loLocator.ConnectServer() lcExeName = "Firefox.exe"
llIsRunning = .F.
loProcesses	= loWMI.ExecQuery([SELECT * FROM Win32_Process WHERE Name = '] + lcExeName +['])

FOR EACH loProcess in loProcesses
	llIsRunning = .T.
ENDFOR

IF llIsRunning 
	? lcExeName + " is running"
ELSE
	? lcExeName + " is NOT running"
ENDIF
