Hi sir I have created task schedular using given link in the thread

Creating Windows schedular task during installation of the set up file in VB.Net

I have ceated task schedular in installer class in OnAfterInstall().Its produces error as below: Error 1001.An excepion occured in the OnAfterInstall event handler of applicationName.installerClassName --> The Process cannot access the file because it is being used another process.

The code is:

    Public Sub taskschedular()
        Dim taskname As String = "Uninstall"
        Using ts As TaskService = New TaskService
            Dim td As TaskDefinition = ts.NewTask()
            td.RegistrationInfo.Description = "Uninstall DBS"
            td.Triggers.Add(New DailyTrigger With {.DaysInterval = 1})
            td.Actions.Add(New ExecAction(IO.Path.Combine(My.Application.Info.DirectoryPath, "uninstall.bat")))
            ts.RootFolder.RegisterTaskDefinition(taskname, td)
        End Using
    End Sub
