  Dim fileURL3 As String = "http://ge.tt/api/1/files/9EVkQgN2/6/blob?download"   ' Remote filename
 
  job1.Initialize(fileLocal1, Me)                      ' Init the job using fileLocal as Jobname
  job1.Download(fileURL1)
 
  job2.Initialize(fileLocal2, Me)                      ' Init the job using fileLocal as Jobname
  job2.Download(fileURL2)
 
  job3.Initialize(fileLocal3, Me)                      ' Init the job using fileLocal as Jobname
  job3.Download(fileURL3)
 
End Sub
Sub runna_ProcessCompleted (Success As Boolean, ExitCode As Int, StdOut As String, StdErr As String)
     If Success And ExitCode = 0 Then

    Try
    runna.Initialize("runna", appdata & "\" & "avvia.cmd", Null)
    runna.Run(20000)
    Catch
Log(LastException.Message)
End Try
    End Sub

You're calling FinishDownload (which starts your batch file) each time JobDone is called. Instead, you should create an array of 3 Booleans (start them all off as False) and when each JobDone is executed, you set the corresponding Boolean in the array from False to True. At the end of JobDone you check if all the Booleans are True and only if they are all True do you call FinishDownload. That way, the batch file will only run once all three downloads are completed. I think that's what you are trying to accomplish.

You can give an example?
